PTFE/PFA Lined Gate Valve

PTFE/PFA Lined Gate Valve (Z41F) APPLICATION
PTFE/PFA Lined Gate Valve is epecially designed for controlling the usual corrosive medium. Its body inner surface is lined with fluorine plastic like FEP/PTFE/PTFE or some other kinds of rubber. It is commonly used in the power generation, brewing, water and food industries and suitable for both gaseous and liquid service. Typically applied in chemical/petrochemical process, food and beverage, and pulp and paper etc. It features ease of maintenance, repeatable on-off, long life durability. PTFE lined butterfly valve is with bi-directional flow and since the valve port corresponds to the piping diameter, a high flow capacity is guaranteed.
