About Valterra 200-15AC PVC Air Check
This Valterra 200-15AC air check valve is made of white schedule 40 PVC (polyvinyl chloride) for strength and resistance to corrosion and mild chemicals. Its EPDM (ethylene propylene diene monomer) seal resists degradation caused by water and oils. It has a maximum pressure rating of 150 pounds per square inch (psi) and a spring tension of 1/4 lb. This air check valve has a 1-1/2" slip connection and a 2" spigot connection that must be fastened with glue. It is suitable for one-directional air flow applications such as pools, spas, and aquaculture. Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. A ball cone valve utilizes a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines. Valterra Products manufactures and distributes valves, hoses, sewer systems, and pool and spa products. The company, founded in 1981, is headquartered in Mission Hills, CA.
