About Smith-Cooper International CV40 Series PVC Check
The Smith-Cooper International CV40 series check valve is made of schedule 40 (standard wall) polyvinyl chloride (PVC) for corrosion resistance, high strength, and less weight than fittings made from metal. It is compatible with schedule 40 PVC pipes and fittings and is suitable for cold-water pressure distribution systems including irrigation, pool and spa, potable water, and chilled water applications. PVC can be connected to other materials such as steel, copper, or cast iron using transition fittings. It has ethylene propylene diene monomer (EPDM) seat and seal, stainless steel spring, spring-loaded poppet, and female National Pipe Taper (NPT) connections on both ends. Female NPT threads connect to male threaded pipes, creating a tighter seal than straight threads. The cracking pressure is 2 pounds per square inch (psi), and the maximum pressure rating is 150 psi.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.Smith-Cooper manufactures a wide variety of pipe fittings and valves. The company is headquartered in Commerce, California, and meets relevant ANSI, ASTM, and International Organization for Standardization (ISO) 9002 standards.
