Shuttle valve body is carbon steel or stainless steel

In the petroleum, chemical, natural gas, heating network, metallurgy, nuclear power, aviation, water network and other fluid transport in various industries are using the check valve prevents fluid backflow. Usually the check valve closed by gravity, the installation location is limited, the sealing performance is poor. Four Chuanjia Wei Fluid  2 way manifolds  Co. developed the shuttle valve to overcome the general lack of check valves to meet the broad needs of various industries. Shuttle valve body is carbon steel or stainless steel. Standard flanged ends. Valves and valve  Stainless steel needle valve  metal seal or soft seal (rubber). Close the valve spool but do not rely on gravity attach an internal preload, so the installation position is not limited. When the shuttle valve before the pressure is less than (or equal to) the pressure valve, the spool valve preload move forward to push off. Even very low back pressure valve is also closed the case very closely. In addition, a buffer spool cavity, slow valve closing speed, which reduces the water hammer pressure shock wave.
