Stainless Steel with Dual Plate and Wafer Check Valve
The purpose of this type of interlock check valve is to allow the medium to flow in only one direction and to prevent the reverse flow.Usually sandwiched check valves operate automatically, and the disc opens under the pressure of a flow of fluid in one direction.Flow in the opposite direction, by the fluid pressure and disc self - coincidence disc on the seat, thereby cutting off the flow.Stainless steel sandwiching check valve belongs to this type of valve, it includes swing check valve and lift check valve.Swing check valves have a medium hinged mechanism and a door-like disc that rests freely against an inclined seat surface.To ensure that the disc reaches the proper seat face each time, the disc is designed in a hinged mechanism so that the disc has enough swing space and true, full contact with the seat.
