Anti Corrosive PTFE Lined Butterfly Valve
MODEL: GLTD371


▪ Lining material: PTFE, PFA, FEP, PO etc.
▪Connection type: wafer, flange, lug etc. 
▪Operation methods: manual, worm gear, electric, pneumatic and hydraulic actuator. 

â–ªThe lined butterfly valves bi-directional flow is possible at maxmium operating pressure. Since the valve port corresponds to the piping diameter, a high flow capacity is guaranteed.
▪ It is outstanding for ease of maintenance and long service life.
▪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.
