Slurry knife gate valve with double acting pneumatic actuator
Design Feature
Coosai Slurry knife gate valve with double acting pneumatic actuator ,Seat of soft seal will use pressure to make disc tightest in
order to achieve the best sealing effect. When disc is fully open,
the 2 sealing seats connect closely and make valve seat complete
seal, and medium can not enter into valve chamber through valve
seat. In this way, it can significantly reduce the medium wash
valve body and disc. Meanwhile, pressure sealed soft seal seat have
good abrasive resistance and corrosion resistance, it can improve
valve sealing effect and working time. And after valve is fully
closed, disc can be removed conveniently (no need to disassemble
the entire valve), and in this way, it will not affect the pipeline
normal operating.
Working conditions: this valve is widely applied for soda ash, paper pulping, mining,
etc. Pressure is usually under 150 Lb and temperature is within
150℃.
Slurry knife gate valve
- Valve work principle:
1. The Slurry kinfe gate valve is a non-packing knife gate valve,
which is sealed through the synthetic rubber sleeve in the valve
chamber For easily worn parts of the valve, the knife ram can be
removed on line for inspection or replacement.
2 Slurry kinfe gate valve is a two-way (two-way seal) product,
installation without considering the flow direction of the medium.
Valve position which direction has the same sealing effect.
Therefore there is no flow indicator arrow or seat side finger on
the valve Indicating arrow.
3. Slurry kinfe gate valve is only used as an on-off valve, which
is not suitable for throttling conditions (the valve shall not be
half-opened and half-closed).
4. All valves shall be used within the design pressure and design
temperature range. If the working condition exceeds the maximum
valve pressure
Or the highest temperature, all consequences by the user's own
responsibility.
Coosai slurry knife gate valve uses 2 pieces design and pressure
sealed soft seal seat. The bottom of disc is wedge design, and
circle arc cross section can not only guarantee pressure sealed
soft seat will not be damaged when valve close, but also can
prevent medium entering into valve chamber during valve open-close.
