main feature

1. The valve seat adopts a sealing ring seal and a floating valve seat structure that applies preload force to make the valve inlet and outlet sealed in both directions. The opening and closing torque of this structure is only 1/3 of that of ordinary valves, making it easy to open and close the valve.

2. The valve seat is made of stainless steel (or cobalt-chromium-tungsten alloy) inlaid or surfacing on the sealing surface, which has double sealing of metal and metal-to-metal. The sealing surface can also remove dirt from the gate plate.

3. For metal-to-metal sealing valves, the outside of the valve body is equipped with a grease injection structure. The grease enters the valve sealing surface through the grease injector and the valve seat, making the valve achieve zero leakage.

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

5. 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 through the hair ball.

6. This valve adopts a packing structure with self-sealing ability, which does not require frequent adjustment. It is extremely light 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 and solving the problem. This eliminates the problem that the general valve packing is most prone to leakage.

7. When the valve is closed, it can automatically remove the high pressure in the inner cavity to ensure safe use.

8. Fully enclosed structure with good protective performance and can adapt to full load working requirements.

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