Description
Check Valves are important part of wellhead equipment and widely used in high pressure lines to control one-way flow and prevent fluid from flowing back to the pump, thus to protect pipeline safety.
Swing check valve is in inner rocker arm swing structure. All switch parts are installed in valve cavity without getting through valve body. Except for the middle flange which is equipped with gasket seal and seal ring, there is no other outside dots. Leakage outside the valve is forbidden.
Swing type check valve rocker arm and valve disc are connected with spherical surface, which make valve disc possess a certain degree of freedom at 360 degree with a proper position compensation. When swing check valve is fully open,fluid pressure is almost unimpeded.
The valve disc of swing check valve is in rotating movement around axis of rotation. Its flow resistance is usually less than that of lift check valve, which is suitable for large bore application.
