General Application Standard Slab Gate Valve with Diversion Hole

Highlight: Slab gate valve with diversion hole

Product introduction:

A slab gate valve is a sliding valve whose closing part is a parallel gate. Its closing part can be a single gate

or a double gate with a spreading mechanism in between. The pressing force of the gate against the valve

seat is controlled by the medium pressure acting on the floating gate or floating valve seat. In the case of a

double-gate slab gate valve, the spreading mechanism between the two gates can supplement this pressing

force. Slab gate valves can be divided into manual slab gate valves, pneumatic slab gate valves and electric

slab gate valves according to the driving mode. According to the application and usage occasions, they can

be divided into slab gate valves with diversion holes, slab gate valves without diversion holes, oilfield slab

gate valves, pipeline slab gate valves, gas slab gate valves, etc.

Product technical parameters:

Product features:

1. Adopting a floating valve seat, bi-directional opening and closing, reliable sealing, and flexible opening and closing.

2. The gate is equipped with guide bars for precise guidance, and the sealing surface is sprayed with hard alloy for erosion resistance.

3. The valve body has a high load-bearing capacity, and the channel is a straight through type. When fully open, it is similar to the straight pipe and passes through the gate guide hole, with very small flow resistance. The valve stem adopts composite packing and multiple seals, ensuring reliable sealing and low friction.

4. When closing the valve, turn the handwheel clockwise to move the gate down to the bottom. Due to the pressure of the medium, the inlet sealing seat is pushed towards the direction of the gate, forming a larger sealing pressure ratio and forming the first seal. At the same time, press the gate towards the sealing seat at the outlet end to form a double seal.

5. Due to the use of double sealing, vulnerable parts can be replaced without affecting pipeline operation. This is an important feature of our factory's products prioritizing similar products both domestically and internationally.
