PTFE Lined Butterfly Valve – ED671-PTFE

Products Description

  • The PTFE Lined Butterfly Valve bi-directional flow is possible at maximum operating pressure. Since the valve port corresponds to the piping diameter, a high flow capacity is guaranteed.
  • It features ease of maintenance, repeatable on-off, long life durability.
  • 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.
  • Lining material: PTFE, PFA, FEP, GXPO etc.
  • Connection type: wafer, flange, lug etc.
  • Operation methods: manual, worm gear, electric, pneumatic and hydraulic actuator.
  • Elite lined three-way ball valves are available as per the needs of applications in additional sizes and other than standard materials.
