Check Valve Overview
Check Valves are automatic shut-off valves that are commonly used for preventing backflow or drainage in a pipe system.Often applied on the discharge side of pumps,check valves prevent the system from draining if the pump stops and protects against backflow, which could harm the pump and/or other equipment.
Dual Plate Check Valve The design of this type of check valve has good structure and appearance.
The discs open under the flow pressure with direction from inlet port to outlet port.When the inlet pressure is lower than outlet pressure, the discs close automatically due to differential pressure and weight of the discs as a result of preventing backflow.
