Wafer Type Single Board Check Valve Stainless Steel

Check valve refers to the opening and closing parts of the circular disc and by its own weight and media pressure generated action to block the media flow back valve. Automatic valve class, also known as check valve, one-way valve, backflow valve or isolation valve. Disc motion is divided into lifting and swing. Lift check valves are similar in construction to globe valves except for the stem that drives the disc. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). Valve is opened when inlet pressure is greater than the sum of disc weight and flow resistance.
