Product features
1. Reduce the rotational torque, support the valve stem, and ensure an effective separation between the valve stem and the valve body to minimize the wear of the valve stem.
2. After polishing treatment, it has a precise fit with the valve seat.
3. Achieve zero leakage requirements for the air tightness test, with small opening and closing torque, and extend the service life of the valve seat.
4. The valve stem seal is not prone to deformation, thus avoiding the common valve stem leakage phenomenon.
5. High precision, strong strength, suitable for the installation of handles and other control devices.
6. Firmly connect the valve stem and valve plate, with vibration and detachment prevention features, and easy to replace.
7. Good integrity, facilitating the opening and closing of the valve plate control.
8. Features include no detachment, anti-tensile, anti-leakage, and convenient replacement.
9. As a device for regulating or cutting off the medium in the pipeline.
10. Suitable for handle control devices (DN50~300), worm gear worm, electric and pneumatic control devices.
