Product Details

Product structure features

1. Reduce the rotational torque, support the valve stem and effectively separate it from the valve body to minimize the wear of the valve stem.
2. After polishing treatment, it fits precisely with the valve seat.
3. Achieve zero leakage requirements for air tightness tests, with low opening and closing torque and extended service life of the valve seat.
4. The valve stem seal is not prone to deformation, thus avoiding the common valve stem leakage.
5. High precision and great strength, suitable for the installation of handles and other control devices.
6. The valve stem and the valve plate are firmly connected, featuring anti-vibration and anti-disengagement, and are easy to replace.
7. It has good integrity and is convenient for controlling the opening and closing of the valve plate.
It features non-detachment, tensile resistance, leakage prevention and easy replacement.
9. As equipment for regulating or cutting off the medium in pipelines.
10. It is applicable to handle control devices (DN50~300), worm gear and worm, electric and pneumatic control devices.
