DUCTILE IRON LOW FLOW PASS PRESSURE REDUCING VALVE (PLDILFPPRV25)

  • Low wleght and short laying length saves initial cost, requires less space, and is easier to install.
  • 200 Micron Fusion Bonded Epoxy Powder Coated internal and external ensured barrier to corrosive chemicals, moisture and humid air.
  • NBR rubber diaphragm to faciliate quiet/Silent operations.
  • Stable Performance, Safe & Reliable.
  • Simple Operation, Convenient Adjusting.
  • Precise Pressure Reducing.
  • Long Service Life.
  • Fluctuating upstream pressure to constant pressure thus smooth water flow.
  • Main valve and bypass valve for low and high flows.
  • Separate adjustment of low Flow-by-Pass and reducing set points
