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 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.
