Product Overview
Q47 type fixed ball valve compared with the floating ball valve, it is working, fluid pressure in front of the sphere of all is passed to the bearing force, will not make a sphere to the seat to move, so the seat will not bear too much pressure, so the fixed ball valve torque is small, the seat of the small deformation, stable sealing performance, long service life, applicable to high pressure, large diameter.Advanced spring pre - seat assembly with ...
Product structure characteristics
A check valve is an “automatic” valve that is opened for downstream flow and closed for counter-flow.Open the valve by the pressure of the medium in the system, and close the valve when the medium flows backwards.The operation varies with the type of check valve mechanism.The most common types of check valves are swing, lift (plug and ball), butterfly, check, and tilting disc.Products are widely used in petroleum, chemical, pharmaceutical, chemica...
