Product Overview

H74 Wafer Single Disc Check Valve in Stainless Steel

What is a Check Valve?
A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. These are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.

Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies of most check valves are made of metal or plastic.
