Stainless Steel Pipe Valve for High Temperature Flue Gas Control in
Large Diameter Pipes
1. Description:
Working principle of the pneumatic flange high temperature
butterfly valve is to control the valve switch through the
pneumatic device.
When the pneumatic device applies pressure, the compressed air
enters the pneumatic device, so that the piston inside it moves,
thereby driving the valve to open and close.
Specifically, when the pneumatic device is closed, the valve is
closed; When the pneumatic device applies pressure, the piston
moves and the valve opens.
By controlling the pressure change of the pneumatic device, the
valve can be controlled.

3. Features:
- Flange connection: The pneumatic flange butterfly valve is
connected with flange, which can be easily connected and
disassembled with the pipeline.
- Flange connection has good sealing performance and can effectively
prevent medium leakage.
- Butterfly plate structure: The valve body of the pneumatic flange
butterfly valve is equipped with a butterfly plate, which can be
rotated with the control of the pneumatic device.
- Rotation Angle of the disc determines the opening of the valve.
- Structure of the butterfly plate is simple, the switch is flexible,
and it can respond to the control signal quickly.
- Sealing performance: The sealing performance of the pneumatic
flange butterfly valve is excellent.
- Metal to metal seal between the disc and the seat can effectively
prevent the leakage of the medium.
- In addition, the surface of the plate can be ceramic coated or
rubber lined to improve sealing performance and corrosion
resistance.
- Fast switching: The switching speed of the pneumatic flange
butterfly valve is fast.
- Due to the structural characteristics of the butterfly plate, the
switching time of the valve is short, which can meet the
requirements of high-speed control.
- Multi-function: The pneumatic flange butterfly valve can be added
according to actual needs of various accessories, such as position
feedback, manual device, etc., so that it has more functions.
- These accessories can improve valve control accuracy and ease of
operation.
- Pneumatic flanged butterfly valves are widely used in fluid control
systems in various industries.
- Petrochemical: Pneumatic flanged butterfly valves can be used in
the transportation and treatment system of petroleum, natural gas
and chemical products.
- Excellent sealing performance and corrosion resistance make it able
to adapt to harsh working environments.
- Power industry: Pneumatic flanged butterfly valves can be used in
coal, gas and nuclear power systems of power stations.
- Fast switching and control characteristics can meet the
requirements of flow and pressure.
- Sewage treatment: Pneumatic flanged butterfly valves can be used
for control and regulation of sewage treatment systems.
