Coal Gas Under Pressure Opening Special Valve
Introduction:
It is mainly used in the case where the opening position is reserved for the pipeline but the opening is required under pressure, so that the valve needs to be installed in advance. It is the gate valve that must be made with a full diameter.
The valve has a long service life, adopts flexible graphite packing, reliable sealing, small flow resistance coefficient, light and flexible operation.
Features:
1. Compact structure, reasonable design, good valve rigidity, smooth channel and small flow coefficient
2. The sealing surface is made of stainless steel and hard alloy, with long service life
3. Adopt flexible graphite packing, reliable sealing, light and flexible operation
4. The driving mode is manual, pneumatic, electric, gear transmission
5. The structural form is elastic wedge single gate, rigid wedge single gate double gate type.
