Fluorine - lined butterfly valve price is significantly lower than corrosion - resistant stainless steel valves and hastelloy valves. Some strong corrosive medium, metal valves can not be used, only the fluorine valve can be used.

Fluorine-butterfly butterfly valve using medium temperature: normally fluorine-butterfly butterfly valve is the use of fluorine plastic FEP, using the medium temperature should not exceed 150 degrees Celsius (medium temperature can reach 150 degrees Celsius, short time for a long period of time should be in suitable temperature 120 degrees Celsius), otherwise, the valve parts of plastic softening, deformation, easily lead to valve closed tightly, large amount of leakage.
If the temperature of the medium used by the user is below 180 deg c in a short time and below 150 deg c in a long time, another kind of fluoroplastic PFA can be selected. However, the price is relatively high, so the inquiry should be made in advance when matching.
Introduction
FREE-VALVE&#;s fluorine lined butterfly valve adopts the central line fluorine lined structure,the valve body and disc are lined with anti-corrosive 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 .
Advantage
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.
