Forged Steel Check Valves are the valves of stopping the fluid from backflow. The disc can be opened by the pressure of fluid. And then the fluid runs from the inlet to the outlet side. When the pressure of inlet is less than outlet, the disc can be closed automatically and stop the fluid from backflow. (Rational Structures, Reliable Sealing; Hard-alloy seal, Long Life).
Series - 150 To 2500
Design Features
