Product features

1. Reduce the torque, support the valve stem, and effectively separate it from the valve body, reducing the wear of the valve stem.
2. After polishing treatment, precise matching with valve seat.
3. Realize zero leakage requirements for air tightness test, small opening and closing torque, and prolong the service life of the valve seat.
4. The valve stem seal is not easy to deform, thus avoiding the usual valve stem leakage phenomenon.
5. High precision, high strength, suitable for the installation of handles and other control devices.
6. Firmly connect the valve stem and the valve plate, with anti-vibration characteristics, and easy to replace.
7. Good integrity, easy to control the opening and closing of the valve plate.
8. It has the characteristics of non-shedding, tensile resistance, leakage prevention and easy replacement.
9. As a device for regulating or cutting off the medium in the pipeline.
10. Suitable for handle control device (DN50~300), worm gear, electric and pneumatic control device.
