Our skilled team of engineers will carefully manufacture check valves tailored to your specifications, considering the material, size, shape, valve box, and strength of the valve body.
Introduction of special cases for dual plate check valves. A check valve (non-return valve) is a valve installed downstream of pressure-generating devices such as pumps to prevent backflow. The valve body opens due to fluid pressure or flow rate, and closes due to a decrease in pressure or flow rate, preventing backflow through spring torque.
