Product Details

                   

Features of flat plate gate valve 

1. The valve seat adopts an O-ring seal and a floating seat structure that applies pre-tightening force to seal the inlet and outlet of the flat gate valve in both directions; and the opening and closing torque of this structure are only 1/2 of that of ordinary valves, which can achieve easy opening and closing. Close the valve

2. When fully opened, the channel is smooth and straight, the flow resistance coefficient is very small, and there is no pressure loss, and the pipeline can be cleaned by the hairball

3. The packing structure with self-sealing capability is adopted, without frequent adjustment, the opening and closing are extremely light, and the sealing performance is reliable. The stuffing box is equipped with an auxiliary sealing grease injection structure, the sealing performance is absolutely reliable, and it can truly achieve zero leakage; it solves the general-purpose The most prone to leakage of valve packing

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

5. Fully enclosed structure, good protection performance, can adapt to all-weather requirements

6. The sealing structure of the valve seat should be elastic and pre-tightened, and the upstream and downstream sealing seats are sealed at the same time. The valve seat and the seal are always face-to-face sealing.

7. The valve seat has a self-cleaning function and is not directly washed by the airflow during the opening or closing of the valve. The valve seat should be made of lubricated, non-wearing material.

8. The failure of the valve actuator will not affect other parts of the valve. Repair and replacement work can be carried out without removing the valve.
