Descripción del producto

FREE-VALVEs pneumatic PTFE lined butterfly valve adopts the central line and PTFElined structure,the valve body and disc are lined with anti-corrosive materials so as to effectively avoid the corrosion of the valve byseriously corrosive media,so the valvehas both the common butterfly valve mechanical strength, and also can play strong resistance to chemical medium properties.With positioner ,it can be used as approximate equal percentage control valve undercorrosive working conditions .

Features

1.The pneumatic valve positioner is used, the proportional adjustment can be achieved, flow characteristic of the valve has approximately equal percentage.

2.PTFE Lined butterfly valve has good sealing performance and is bi-directional flow for zero leakage.

3. PTFE 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. It has small torque and easy to operate,it can be installed in any direction.

5. Convenient remote control operation, precise control,automation.
