Flat Gate Valve

Description

Flat gate valves are particularly suitable for media with demanding sealing requirements in the chemical, petrochemical and steel industries.

Features:
1. Adopt floating valve seat, two-way opening and closing, reliable sealing and flexible opening and closing.n2. The ram has guide strips for precise guidance, and the sealing surface is spray-welded with cemented carbide, which is resistant to erosion.n3. The valve body has high bearing capacity, and the channel is straight-through. When fully open, it is connected with the gate guide hole and is similar to a straight pipe, and the flow resistance is very small. The valve stem adopts composite packing and multiple seals, making the seal reliable and low friction.n4. When the valve is closed, turn the handwheel clockwise, and the gate moves down to the bottom. Due to the action of the medium pressure, the sealing seat at the inlet end is pushed toward the gate to form a larger sealing specific pressure, thereby forming a seal. At the same time, the gate is pressed against the sealing seat at the outlet end to form a double seal.n5. Due to the double seal, the wearing parts can be replaced without affecting the pipeline work. This is an important feature that our products have priority over similar products at home and abroad.n6. When opening the gate, rotate the handwheel counterclockwise, the gate moves, and the diversion hole is connected with the passage hole. As the gate rises, the through hole gradually increases, and when it reaches the limit position, the diversion hole coincides with the passage hole, and it is fully opened at this time.
