FREE-VALVE’s Pneumatic PTFE Lined Butterfly Valve adopts the central line fluorine lined structure,the valve body and disc are lined with anticorrosive materials so as to effectively avoid the corrosion of the valve by strong corrosive media,so the valve has both the common butterfly valve mechanical strength, and also can play strong resistance to chemical medium properties .
Features
1.The valve positioner is used, the proportional adjustment is achieved, flow characteristic of the valve has approximately equal percentage,
2.Lined butterfly valve has good sealing performance and is bi-directional flow for zero leakage.
3. Broad lined materials of body and trim for a variety of medium service,the valve is an ideal solution to control and shut-off applications
4.The valve can be equipped with various types of electric actuators
5.It has small torque and easy to operate,it can be installed in any direction.
