Product Description

Wafer Type PTFE/PFA Lined Butterfly Valve ( D71F)

Product Description

PTFE/PFA Lined Concentric Butterfly 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. The concentric design 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.

Application

PTFE Lined Butterfly Valve can be divided into Fully Lined and Half Lined. Fully PTFE Lined Butterfly Valve refers to the Butterfly Valve with Fully PTFE Lined Valve Disc & Fully PTFE Lined Valve Seat. Half PTFE Lined Butterfly Valve referes to the Butterfly Valve with Disc Lining or Valve Seat Lining.
