Product Details

Technical standards

1. As a device for regulating or cutting off the medium in pipelines.
2. It is applicable to handle control devices (DN50~300), worm gear, electric and pneumatic control devices.
3. The design and manufacturing standards comply with GB/T12238.
4. The pressure test complies with GB/T13927.
5. The structural length complies with GB/T12221.
6. The side flange standard complies with GB/T17241.6.

Product features

1. It can be equipped with a handle, worm gear transmission, electric or pneumatic control devices.
2. Reduce the torque of rotation, support the valve stem, and make it effectively separated from the valve body to reduce the wear of the valve stem.
3. After polishing treatment, it has a precise fit with the valve seat.
4. Achieve zero leakage requirement for the air tightness test. The opening and closing torque is small, prolonging the service life of the valve seat.
5. The valve stem seal is not prone to deformation, thus avoiding the common valve stem leakage phenomenon.
6. High precision, strong strength, suitable for installation of handles and other control devices.
7. Firmly connects the valve stem and valve plate, with features of anti-vibration and anti-detachment, and easy to replace.
8. High precision, strong reliability, convenient for controlling the opening and closing of the valve plate.
9. Good overall support, stable fixation, resistant to tension and leakage.
10. Assist in preventing end shaft leakage.
