Triple eccentric metal hard seal butterfly the structure advantages of pneumatic valve 1

switch torque is small, the structure is unique. 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.
triple eccentric multi-layer metal hard seal butterfly butterfly plate of pneumatic valve sealing ring for soft hard cascading sequins, upper and lower parts of the pneumatic valve stem bushing. With metal sealing and elastic sealing the dual advantages of no matter under the condition of low temperature and high temperature, has excellent sealing performance.
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.
pneumatic seat and disc almost no friction, three-dimensional eccentric structure. Closed when the pneumatic valve internal parts almost no damage; This structure is greatly improves the performance of the pneumatic valve in use. And has the close tight sealing function.
the surfacing alloy steel or too set carbide, pneumatic valve sealing surface. Sealing surface wear resistance, resistance to erosion and corrosion; Long service life.
