The closing member of slab gate valve may be a single gate or a double gate with a split mechanism in between.The pressure of the ram against the seat is controlled by the medium pressure acting on the floating ram or seat.

When the valve is closed, turn the handwheel clockwise and the gate moves down to the bottom. Due to the action of medium pressure, push the seal seat at the inlet end to the direction of the gate to form a larger seal specific pressure, thus forming the first seal.At the same time, ram pressure to the outlet end seal seat, as a double seal.

When the gate is opened, rotate the handwheel counterclockwise, the gate moves up, and the diversion hole is connected with the passage hole.With the rising of the gate, the through-hole gradually increases, and when it reaches the limit position, the diversion hole coincides with the passage hole, and then it is fully open.


1. Floating valve seat, bidirectional opening and closing, reliable sealing, flexible opening and closing;

2. The gate is provided with guide strip for precise guidance, and the sealing surface is sprayed with cemented carbide for erosion resistance;

3. High bearing capacity of valve body, passageway is straight, when fully open, it is similar to the gate orifice and straight pipe, and the flow resistance is small;

4. Stem with compound packing, multiple seals, making the seal reliable, low friction;

5. Because of the use of double sealing, vulnerable parts can be replaced without affecting the work of the pipeline.
