Flat gate valve is a sliding valve with a parallel gate as the closing element. The closing component can be a single gate or a double gate with a support mechanism in between. The clamping force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or floating valve seat. If it is a double gate flat gate valve, the expansion mechanism of the two gate valves can supplement this clamping force.

feature

1. The valve seat adopts an O-ring seal and a floating valve seat structure with pre tension force, which enables bidirectional sealing of the inlet and outlet of the flat gate valve; And the opening and closing torque of this structure is only half of that of ordinary valves, which can achieve easy opening and closing of valves.

2. When fully open, the channel is smooth and straight, with a very small flow resistance coefficient and no pressure loss, allowing for the cleaning of pipelines with a ball.

3. Adopting a packing structure with self sealing ability, it does not require frequent adjustment, and the opening and closing are extremely lightweight with reliable sealing performance. The packing box is equipped with an auxiliary sealing grease injection structure, which ensures absolute reliable sealing performance and truly achieves zero leakage; Solved the problem of easy leakage at the packing of universal valves.

4. When the flat gate valve is closed, it can automatically release the high pressure inside the chamber to ensure use.

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

Suitable occasions for flat gate valves

1. (Class 150-900/PN1.0-16.0MPa, working temperature -29~121 ℃) Petroleum and natural gas transmission pipelines. Flat gate valves with diversion holes are also convenient for cleaning pipelines. 2. Transportation pipelines and storage equipment for finished oil products. 3. Oil and gas extraction wellhead equipment, also known as Christmas tree valves. 4. Pipelines containing suspended particles. 5. Urban gas transmission pipelines. 6. Water supply project.
