Triple eccentric metal hard seal butterfly summary of pneumatic valve 2)

triple eccentric metal hard seal butterfly pneumatic
the rubber sealing butterfly valve pneumatic valve faults are throttling, due to the improper use will produce cavitation occurs, rubber peeling, damage. Therefore, to solve the problem of cavitation was born of a new generation of metal sealing butterfly pneumatic valve. , triple eccentric multi-layer metal hard seal disc pneumatic valve pneumatic butterfly valve seal hard, soft layer of metal and metal sealing ring, sealing the dual advantages of flexibility, no matter under the condition of low temperature and high temperature, not only has excellent sealing performance. , using three-dimensional eccentric structure, pneumatic seat and disc almost no friction, when the pneumatic valve closing almost no damage to internal parts, this structure has greatly increased the use of the performance of the pneumatic valve. Closed more and more tightly with sealing function. , in the upper and lower stems with casing, each small bushing wear, friction, this structure can prevent wear and adhesion, can also improve your life. , pneumatic valve seal welded steel or stellite, hard seal butterfly pneumatic valve sealing surface wear resistance, corrosion resistance, surface corrosion resistance, long service life. , unique structure, the switching torque is small, flexible operation, energy saving, convenient and a free press, high voltage, low power and reliable sealing performance. Can be used to open and regulating equipment.
