BRONZE PRESSURE REDUCING VALVES (PLBNPRV25)

  • PRVS enable control of pressure from boosted cold water supplies to match site requirements.
  • Light, compact in constructions & short installed length.
  • No influence on outlet pressure by fluctuating inlet pressure.
  • Screw with knob for setting outlet pressure.
  • The adjustment spring is not in contact with the medium.
  • Greater flow performance with lower fall off pressure for consistent operation.
  • Excellent controllability.
  • Lead content of the Valve PBS2% ensure suitability of the material for potable water applications.
