Z43H Flat Gate Valve Without Diversion Hole

One. Structure and characteristics

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 is 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 extremely small, and there is no pressure loss, and the pipeline can be cleaned with a hair ball.

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. There is an auxiliary sealing grease injection structure at the stuffing box, the sealing performance is absolutely reliable, and the zero leakage is truly achieved; 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 inner cavity can be automatically removed to ensure safe use.

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