Pneumatic valve adopts multi-layer metal hard seal butterfly solve the problem of cavitation

rubber seal butterfly pneumatic valve fault is for the use of throttle, due to the improper use will produce cavitation, make rubber peeling, damage, etc. Therefore, solving the problem of cavitation of a new generation of metal sealing butterfly pneumatic valve was born. A, triple eccentric multi-layer metal hard seal butterfly butterfly plate of pneumatic valve sealing ring for soft hard cascading sheet metal, metal sealing and elastic sealing the dual advantages of no matter under the condition of low temperature and high temperature, has excellent sealing performance.
b, using three-dimensional eccentric structure, pneumatic valve seat and disc almost no friction, pneumatic valve internal parts when closing almost no damage; This structure is greatly improves the performance of the pneumatic valve in use. And has the close tight sealing function.
c, in the upper and lower parts of the pneumatic valve stem bushing, and each bushing wear and friction resistance is very small, the structure can prevent wear and adhesion, and at the same time increase the service life.
d, pneumatic valve sealing surface surfacing welding alloy steel or department too hard alloy, stainless steel hard seal butterfly pneumatic valve sealing surface wear resistance, resistance to erosion and corrosion; Long service life.
e, unique structure, low torque, flexible operation, energy saving, convenient and not affected by medium pressure high, low, sealed performance is reliable. Can be used for opening and closing and regulating equipment.
