Widely used in petroleum, chemical, pharmaceutical, power and other industries. At the nominal pressure ≤ L, pipeline, water, oil, steam medium 0MPa, open and close by.
Product features:
■ valve with two mutually parallel and wedge gate locking device sealing structure
A valve sealing parts are separated from each other, causing deformation is also able to ensure the seal even when the temperature changes, and not because of the high temperature expansion and make the wedge squeeze not open;
■ valve seal with wear and corrosion resistant material, prolongs the service life of the valve;
■ in high-temperature, high-pressure situations, the import side of the damper is designed to pressure relief mode, prevent the abnormal high pressure phenomenon caused by the change of temperature, to ensure safety.
