1-1/4" Check Valve Carbon Steel Body/Alum. Internals/Buna Seal 200 PSI

Check valves are an essential part of industrial equipment for air and water applications. With few moving parts to wear out, these valves withstand the frequent opening and closing of pulsating flow and rapid flow reversal. They open to allow flow in one direction and close when flow stops or reverses. Without the use of a check valve most mechanical equipment would be damaged when the pressure drops or the system shuts off, and the flow is reversed.
