Technical features

1. The valve body has two structures: casting and welding

2. The valve seat adopts O-ring sealing and floating valve seat structure with preload force, so that the valve inlet and outlet are sealed in both directions; and the opening and closing torque of this structure is only 1/2 of that of ordinary valves, which can easily open and close the valve.

3. The valve seat adopts PTFE inlaid on the sealing surface, which has double sealing of PTFE to metal and metal to metal. The PTFE sealing surface also removes the dirt on the gate.

4. For metal-to-metal sealed valves, the valve body is equipped with a grease injection structure on the outside. The grease enters the valve sealing surface through the grease injector and the valve seat, so that the valve achieves zero leakage.

5. The gate of the valve with diversion hole always matches the sealing surface whether it is fully open or fully closed, and the sealing surface is protected from direct erosion by the medium, thereby extending the service life.

6. When the valve is fully open, the channel is smooth and straight, the flow resistance coefficient is extremely small, there is no pressure loss, and the pipeline can be cleaned by the hair ball.

7. This valve adopts a packing structure with self-sealing ability, which does not need to be adjusted frequently. It is extremely easy to open and close, and the sealing performance is reliable. The stuffing box is equipped with an auxiliary sealing grease injection structure, and the sealing performance is absolutely reliable, truly achieving zero leakage; it solves the problem that the packing of general valves is most likely to leak.

8. When the valve is closed, the high pressure in the inner cavity can be automatically unloaded to ensure safe use.

9. The fully enclosed structure has good protection performance and can adapt to all-weather requirements.

10. The valve is equipped with an indicator rod or observation window to indicate the opening and closing status of the valve.
