Product Details

Product Structure Features

1.Driving device：Can be equipped with a handle, worm gear, electric or pneumatic control device.

2.Bushing：Reduce the rotational torque, support the stem, and make it separate from the body effectively, reduce the wear of the valve stem.

3.Surface of disc axle hole：After polishing treatment, with the seat precision.

4.High precision disc external profile：To achieve zero leakage requirements of air tightness test. The opening and closing torque is small, prolong the service life of the seat.

5.Stem seal：Stem seal is not easy to deform, thereby avoiding the usual stem leakage.

6.Strong precision key：The utility model has the advantages of high precision and high strength, and is suitable for the installation of the handle and other control devices.

7.Precision taper pin：The utility model is characterized in that the valve rod and the valve plate are firmly connected with the valve plate, and the utility model has the characteristics of anti vibration and easy replacement.

8.Integral stem design：High precision, high reliability, easy to control the opening and closing of the valve plate.

9.Body lined with rubber seat:Good overall stability, stable, tensile, anti leakage.

10.O-ring:Auxiliary shaft end leakage.
