To achieve the maximum possible flow, internal components are designed to reduce flow resistance. These valves open to allow flow in one direction and close when flow stops or reverses. A removable cap provides easy access to internal components for maintenance.
316 Stainless Steel Body—316 stainless steel valves are more corrosion resistant than bronze valves.
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.
