EPDM

CPVC (chlorinated polyvinyl chloride) is a type of PVC that has a higher temperature tolerance; it is rated for temperatures up to 200F (93C). Many users prefer it to regular PVC for this reason. Our CPVC true union ball check valves provide a high quality, easy-to-maintain solution for anyone who needs a check valve in their piping system. The EPDM (ethylene propylene diene monomer) O-ring is tough and long-lasting, providing a reliable seal up to 150psi working pressure.

CPVC EPDM true union ball check valves are used to ensure fluid only passes one way through a system, hence the word “check” in their name. “True union” is a term that is often used in valves to indicate that it can be taken apart. The multi-part body of these true union valves allows certain parts to be replaced without having to get a whole new valve. It also means that cleaning and maintenance are easy.

Ball check valves are just one type of check valve. Many different types of check valves exist, but they all have different uses they are best suited for. These ball check valves use a half-ball seating. Liquid is allowed to pass through when it pushes against the spherical side, but the valve is forced closed when fluid hits the other side, which is concave and catches water. This is different from a regular ball valve, which requires manual operation to open or close. In a ball check valve, the fluid in the system does all the work. These types of valves have different uses and should not be confused.

EPDM stands for ethylene propylene diene monomer and is a specific type of rubber that is often used in O-rings such as the ones found in these valves. It is a high-quality, low cost material that is rated for use with a variety of materials. What makes EPDM stand out is its ability to resist the degrading effects of weathering, ozone, and UV ray exposure.
