What is double plate swing check valve
Main features of Double plate swing check valve: Two valve plates are fixed on the valve body along a pivot axis, and two springs are installed on the butterfly plate above the sealing surface. Driven by the pressure of the medium flow, the spring is compressed to force the butterfly plate to open. When the […]
What is a Single-disc swing check valve

What is a single plate check valve
Single-plate check valve is also called single-disc check valve, wafer check valve: it is a valve that can automatically prevent fluid backflow. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side […]
Materials, installation and features of vertical check valve
Part materials of vertical check valve: Construction and installation points for vertical check valve: 1) The installation position, height, and direction of inlet and outlet must meet the design requirements. Note that the direction of medium flow should be consistent with the direction of the arrow marked on the valve body, and the connection should […]
Use performance and working principle of vertical check valve
