Reliable Sealing And Flexible Opening And Closing Flat Gate Valve
Product introduction:
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 supporting mechanism between them. The clamping force of the gate towards 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 opening mechanism between the two gates can supplement this clamping force.
Flat gate valves can be divided into manual flat gate valves, pneumatic flat gate valves, and electric flat gate valves according to their driving methods. According to their purpose and usage, they can be divided into flat gate valves with diversion holes, flat gate valves without diversion holes, oilfield flat gate valves, pipeline flat gate valves, and gas flat gate valves.
Our flat gate valve series products adopt a new floating sealing structure, suitable for oil, natural gas and other pipelines with a pressure not exceeding 15.0MPa and a temperature of -29~121 ℃. As a control medium for opening and closing and regulating devices, this product has a novel structural design, appropriate material selection, strict testing, and easy operation. It has strong anti-corrosion, wear-resistant, and erosion resistance performance, making it an ideal new type of equipment in the petroleum industry.

Product features:
1. The flow resistance is small, and the flow resistance of non shrinking pipes is similar to that of short pipes.
2. The flat gate valve with a guide hole can be installed on the pipeline and can also be cleaned directly with a pipe cleaner.
Due to the sliding of the gate on two valve seat surfaces, the flat gate valve fluid can be suitable for media with suspended particles.
