F304 Piston Check Valve,API 602,DN40,600 LB,RF End

Descrição

F304 Piston Check Valve

A forged steel check valve utilizes the medium’s flow to automatically open and close the valve disc, preventing reverse flow. Also known as a check valve, one-way valve, reverse flow valve, or back pressure valve, it ensures proper function with a body guide that aligns the seat and disc. When closing, the flow pressure forces the disc off the seat, enabling fluid to pass through the valve.
