McMaster 4894K12 High-Cycling Threaded Check Valve, Bronze, 3/4 NPT Female, Class 125, 5.24 Cv

With few moving parts to wear out, these valves withstand frequent opening and closing, pulsating flow, and rapid flow reversal. They open to allow flow in one direction and close when flow stops or reverses. All have a removable cap that provides easy access to internal components for maintenance.

Flow Coefficient (Cv) — Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Warning: Chemical compatibility must be determined by the customer based on the conditions in which the product is being used, including the presence of other chemicals, temperature, and consistency.
