  • Difference Between Stainless Steel and Brass Valves



     

    When choosing the correct valves for your project, deciding between stainless steel valves or brass valves is very important. Because of the differences in the materials, one is often better suited for a project than the other. There are several types of valve materials on the market, however this article will focus on a comparison of stainless steel valves and brass valves.

    Brass Valves

    Brass is a copper alloy which means that it is stronger than plastic. This additional strength makes them, though not the most expensive option for valve, more expensive than PVC or plastic valves.

    Brass is a mixture of copper and zinc, and occasionally other metals. Because of its nature as a soft metal, it is able to resist corrosion very well as opposed to plastic valves. Brass is also able to absorb and withstand more heat than plastic, making brass valves an optimal choice for at home plumbing systems.

    One significant difference between stainless steel and brass valves is that brass valves tend to accept welding better than stainless steel valves. This offers some versatility. However, brass valves do have some drawbacks.

  • Common Uses for Camlock Couplings



    Camlock couplings, also referred to as cam and groove fittings, are becoming increasingly popular in many industries. The innovative technology of the camlock coupling provides a simple and reliable method for connecting and disconnecting hoses without the use of extra tools. Not only are they amazingly easy to use (see a video on how to use camlock couplings here), they are also extremely versatile and are suitable for a variety of different settings and purposes.B-style coupling

    Camlocks are heavy duty couplings. As a result, these handy tools can be used in homebrew, agricultural, military, and industrial environments.  The most common uses for camlock couplings take place in industrial environments because hoses in industrial settings tend to be of larger diameters.

    Camlock Applications

    Camlock couplings are great for the transfer of both dry and fluid materials. There are a variety of camlock uses, such as transferring food, water, fuel, or sand and making them suitable for almost any industry. Because of the variety of substances that can flow through the camlock, it is important to choose the right material for the job. Common camlock applications and their materials are:

    • Stainless Steel Camlocks are best suited for acid, alkali, and corrosive substances.
    • Polypropylene and Nylon Camlocks can be used in the chemical industry, for transmitting liquid, and for irrigation in the agricultural industry.
    • Brass Camlocks work very well for transmitting salty water. They are suitable for most environments except for acid and alkali.
    • Aluminum Alloy Camlocks are great for use with fresh water or mixtures of oil and water.

    While Camlock couplings are extremely versatile, there are some types of substances that are not suitable for use with any type of camlock couplings. Cam and groove couplings should not be used for steam applications. Using Camlocks for steam is very dangerous and could result in an explosion. For more information about why camlocks should not be used with steam, visit the Industrial Knowledge Zone.

    Camlock Coupling Styles and Sizes

    The style is very important when deciding which camlock to use. The camlock uses vary from style to style in the same way as with the materials. Below is a brief description of the different types of camlock styles you can encounter: A-Style Coupling

    • A: male adapter with a female thread
    • B: female coupler with a male thread
    • C: coupler with a shank (hose barb)
    • D: coupler with a  female thread
    • E: adapter with a shank
    • F: adapter with a male thread
    • DC: dust cap
    • DP: dust plug

    Camlock couplings are handy tools that can benefit so many products. It is very important to understand camlock applications so that you can choose the proper tool for the job. Another important factor in the selection of camlock, is selecting the correct size for the job. Check out our article on how to choose the right size camlock coupling here.

  • Ordering the Right Size Cam Coupling



     

    Camlock couplings (also known as cam couplings, camlock fittings or cam and groove couplings) are handy tools that allow the user to connect and disconnect joints in a pipe line quickly and efficiently. The use of camlock couplings is essential in order for hoses and pipes to function properly. But ordering the right size cam coupling can be difficult.

    When using camlock couplings, it is important to know how to order a camlock coupling of the appropriate size for your project. When choosing a coupling, is important to understand the distinctions between the sizes and understand how to measure a camlock fitting.

    For the female part of the coupling, (also known as the coupler) the size is obtained by measuring the diameter of the open end, or inside diameter (ID). For the male part of the coupling (adapter), the size is obtained by measuring the diameter of the adapter end or outside diameter (OD).

    How to Measure a Camlock Fitting

    Always ensure that the inside diameter and outside diameter of your coupler and adapter match. Also, ensure that you have the correct size couplings for the size of your pipe. The tables below (which were built using info from this helpful site) detail the proper sizes to use for your projects.

    Our selection of camlock couplings includes polypropylene, nylon, and stainless steel couplings. Besides the correct size of camlock couplings, it is also important to choose the best material for the project at hand. Each material provides a unique range of benefits.

    Polypropylene and nylon couplings are both inexpensive, leakproof and light weight. Polypropylene, however is of lower density and is anti-acid. Nylon has higher density and provides heat resistance. The agricultural industry benefits greatly from their ability to transmit liquids.ordering the right size cam coupling

    While slightly more expensive, Stainless Steel cam couplings provide immense durability and anti-corrosion advantages, as well as high strength and temperature resistance. They are recommended for highly corrosive areas.

    How to Order a Camlock Coupling

    Whichever you choose, ordering the right size camlock coupling can make or break the success of a project. Before shopping, make sure that you know:

    1. The material that best suits your project. (Where will you be using the material and for what purpose? What is your budget?)
    2. How to measure your camlock fitting or pipe size. Ensure you know the necessary Threaded inside or outside diameter for the fitting.
    3. That you know how to order a camlock coupling. Find a reputable distributor, such as PVC Fittings Online that carries the size and material that you will need!

  • When to Use Metal Valves - Common Metal Valve Applications



    stainless steel gate valveBefore discussing metal valve uses and the various jobs they do well, we should acknowledge the fact that many types of metals exist. Just like the category of "plastic" covers PVC, CPVC, ABS, polypropylene (PP), etc., "metal" includes cast & ductile iron, brass, bronze, carbon & stainless steel, and more! Knowing exactly when to use metal valves requires knowledge of the metal and the medium.

    This blog post discusses different metal valve applications that, for one reason or another, plastic valves cannot handle. Countless specific jobs exist for metal valves, but we will focus on a broader view of applications. Diving into every single job would take far too long. But let's dig deeper into the different materials used and when to use metal valves!

  • Common Uses for Butterfly Valves



     

    CPVC butterfly valve lug styleUsing PVC valves to control water in a system is not difficult and can be extremely rewarding when done correctly. These valves are especially useful in home irrigation & gardening systems, homemade fish tanking piping, and other such home applications. Today we will be looking at a few different butterfly valve applications and why these pieces of equipment are so useful.

    Many valves are made from PVC or CPVC including butterfly valves, ball valves, check valves, and more. Each type has it's own strengths and weaknesses, but butterfly valves are unique in their body style and the way they regulate flow. With a quarter-turn disc that sits amid liquid flow even while open, nothing else is quite like a butterfly valve. Further down we will discuss "wafer butterfly valves vs. lug butterfly valves," but first let's look at some uses for butterfly valves!

    Common Butterfly Valve Applications

    Butterfly valves are a quarter-turn valve that has a plastic or metal disc in the middle that rotates on a metal rod or "stem." If the stem is the body of the butterfly, then the disc is the "wings." Because the disc always sits in the middle of the pipeline, the fluid is slowed slightly as it rushes through an open valve. The following examples are a few jobs -- some specific and some general -- that butterfly valves are perfect for!

  • Bronze vs. Brass Valves: What's the Difference?



    Bronze and brass are easy to get confused. They look similar, have similar-sounding names, and are used for many similar applications. These materials, while sharing many positive qualities, are not identical. There is more than one difference between bronze and brass valves, but not everybody knows about them. While both materials are alloys that incorporate a generous amount of copper, they differ in price and properties.

    What is Bronze?

    bronze vs. brass valvesBronze is one of the original metal alloys. Using copper and tin, metal workers developed a material that was both strong and malleable, meaning it would not crack as easily as something like iron. Bronze has not changed very much, aside from the reduced amounts of lead and the occasional addition of manganese, aluminum, or nickel. Parts made of this material can only be manufactured by casting the material into a mold or by machining a pre-cast bronze ingot.

    Bronze has a rough, porous exterior with small cavities in the surface. This is due to the casting process. However, bronze alloys with select additives can hold a polish and are not as abrasive. Bronze has many benefits, including high ductility (resists cracking), corrosion resistance, and low cost. There are tons of uses for bronze valves, including safety relief, flow direction control, shutting off flow, and more! Lead free bronze valves for potable water are available, but they must meet or exceed Clean Water Act lead restrictions.

  • Malleable vs. Ductile Iron



    black malleable iron elbow fitting
    People know us for our plastic products (hint: it's in our name), but we are fans of everything to do with piping. Metal pipe, fittings, valves, and filters are no exception! This blog post is titled "Malleable vs. Ductile Iron" and will lay out a comparison between malleable and ductile iron.

    You may be thinking, "If they're both iron, they should behave basically the same, right?" That's a great question, but the answer is no. These are two iron alloys with different chemical compositions, so you cannot always use them interchangeably. First, we will look into the history of these materials. Then we will lay out the physical properties of each material. Finally, we will investigate common applications for each material.

    Iron History

    Humans have been manipulating iron to build things for centuries, maybe even millennia. However, most improvements to iron are somewhat modern. Until recently, the strongest types iron were "gray" and "white" cast iron. To make cast iron equipment, molten iron was molded in a cast. They had to do this because hammering cast iron breaks it. Gray and white iron were structurally sound, but cracked if bent or expanded.

    Malleable iron was the first iteration that could be hammered and bent into shape. This made it much easier to work with and less likely to fail. In 1943, however, ductile iron was developed. The difference between malleable and ductile iron was toted to be strength. This would allow ductile iron to be more easily bent and manipulated without breaking. So which material is actually better? Let's list their physical properties.

  • Block Valve: What It Is & How It's Used



    If you've ever read our blog, you may know a thing or two about valves. We've posted an overview of butterfly valves, guides to cleaning and fixing ball valves, and even a semi-comprehensive list of the most common types of valves. Until now, however, we have not mentioned block valves. But the term "block valve" describes many of the valves we've talked about.

    The strictest definition of "block valve" (or shutoff valve) refers to it as "any valve that has the capacity to block movement in one or more directions." Usually, however, people use the term when referencing a valve that can totally prevent or allow motion. This means that a block valve should A) be able to completely stop flow when closed and B) allow fluid motion to happen unrestricted when open. Flow is either completely allowed or completely denied when a block valve is in action.

    In this post we will cover the most common types of valves that fall under the "block valve" umbrella. This could help you when choosing block valves for your next project!

    Types of Block Valves

    An important detail about block valves is that their name is not an official classification of a specific type of valve. Rather, it is a broad description of several types of valves that are designed to block flow.

    Several valves immediately disqualify themselves from being block valves due to their design. Globe valves are a type of control valve that, because of their design, limit flow regardless of how far open they are. The same is true of butterfly valves, which have discs right in the middle of the pipeline. The following are a few types of valves that have block valve characteristics.

    Ball Valves

    PVC ball valve with red handleBall valves are probably the most common type of valve there is, especially in the PVC applications we tend to see.These valves are usually used to totally turn on/off flow in a system using a spherical seating with a hole in it. This hole allows liquid to flow through when the valve is in the "on" position.

    Some ball valves are available in "full-bore" configurations, which means the hole in the ball is the same diameter as the pipeline. Full-bore ball valves are perfect examples of block valves, as they are not ideal for slowing down or limiting flow, but excel at completely stopping it and letting it pass uninterrupted. Ball check valves are not block valves, as they typically limit flow even when being pushed open by liquid.
