BUTTERFLY VALVE :

PHIXER BUTTERFLY VALVE meets the specifications of AWWA C504. The single design allows all components to be standardized for convenience and flexibility. The size range offered is 350 mm (14in.) to 2600 mm (104 in). The heavy-duty construction is designed for dependability and long-term service.

The valve features include:
  • A bubble-tight 360° rubber ring seal set at the factory to assure a positive seal, with a final leak test to confirm the seal's tightness.
  • A replaceable body seat, where the rubber seat is vulcanized to a metal ring (350 mm-1000 mm) and can be easily replaced by removing the retaining ring.
  • Reduced maintenance due to the double eccentric design, which offers a long service life.

GENERAL SPECIFICATIONS :

  • Sizes...350 mm (14 in) to 2600 mm (104 in)
  • Maximum Working Pressure: 10 bar (150 psi)
  • Shell Test Pressure (For Body): 20 bar (300 psi)
