Product Features

1.Can be equipped with a handle, worm gear, electric or pneumatic control device.
2.Reduce the rotational torque, support the stem, and make it separate from the valve body effectively, reduce the wear of the valve stem.
3.After polishing treatment, with the valve seat precision.
4.To achieve zero leakage requirements of air tightness test. The opening and closing torque is small, prolong the service life of the valve seat.
5.Stem seal is not easy to deform, thereby avoiding the usual stem leakage.
6.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.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.High precision, high reliability, easy to control the opening and closing of the valve plate.
9.Good overall stability, stable, tensile, anti leakage.
10.Auxiliary shaft end leakage.
