The slab gate valve is a member of the gate valve family, which is the same as the wedge gate valve; its main function is to control the on-off of the pipeline, not to adjust the flow of the medium in the pipeline.

Product structure features of slab gate valve:

1. The valve seat of slab gate valve adopts O-ring sealing and floating valve seat structure with pre-tightening force, so that the inlet and outlet of the valve are sealed in both directions; and the opening and closing torque of this structure is only that of ordinary valves, which can achieve easy opening and closing. Close the valve.

2. The valve seat of slab gate valve is inlaid or surfacing stainless steel (or cobalt-chromium-tungsten alloy) on the sealing surface.

3. The metal-sealed valve has a grease injection structure outside the valve body. The grease enters the valve sealing surface through the grease injector and the valve seat, so that the valve can achieve zero leakage.

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

5. When the slab gate 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. The slab gate valve adopts the packing structure with self-sealing ability, which does not need to be adjusted frequently. It is very easy to open and close, and the sealing performance is reliable. There is an auxiliary sealing grease injection structure at the stuffing box, which has reliable sealing performance and truly achieves zero leakage; It solves the disadvantage that the general valve packing is easy to leak.

7. When the slab gate valve is closed, the high pressure in the inner cavity can be automatically removed to ensure safe use.

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

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