Brief Introduction.
PTFE Lined Wafer Lug Type Pneumatic Control Butterfly Valve is a valve (valve plate) rotating around fixed axis perpendicular to the channel, the piston type double or single action (spring reset) pneumatic actuator and the butterfly valve, belonging to the rotating high performance control or cut off the valve, the valve is used with electric - gas valve positioner or the electromagnetic valve, air filter regulator, limit switch (valve position), which can realize the fluid process pipeline in the proportion regulation and two cut-off control, automation control so as to achieve the parameters on the fluid flow, pressure, temperature, liquid level etc.. Widely used in gas, liquid, thick slurry or powder, suspended particles such as medium.Field of Application.
