Z641H pneumatic gate valve is widely used in petroleum, chemical, hydraulic, thermal power plants and other oil and steam pipelines as opening and closing devices for connecting or cutting off the medium in the pipeline. It is suitable for piping system with nominal pressure PN1.6～16.0MPa and working temperature ≤-29℃～550℃, as the medium for cutting off or connecting the pipeline. Applicable media are: water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc.
Z641H, Z641Y, Z641W pneumatic gate valves, with the help of compressed air-driven valves, when the gate valve is closed, the sealing surface can only rely on medium pressure to seal, that is, rely on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure sealing The sealing of the surface is self-sealing. Most gate valves adopt forced sealing, that is, when the valve is closed, the gate must be forced against the seat by external force to ensure the sealing performance of the sealing surface.
Features:
1. Compact structure, reasonable design, good valve rigidity, smooth passage and small flow coefficient
2. The sealing surface is made of stainless steel and hard alloy, with long service life
3. Using flexible graphite packing, reliable sealing, light and flexible operation
4. The driving mode is manual, pneumatic, electric, gear transmission
5. The structure is elastic wedge single ram, rigid wedge single ram and double ram type
