PR-HF
Pressure Regulator


Specifically designed for copper or gold/silver mining solutions with up to 4.0 pH on installations requiring higher flows 10 to 32 gpm (2271 to 7268 L/hr) to maintain a constant preset outlet pressure while handling varying inlet pressures.

 

Features:

  • Maintains a constant preset outlet pressure while handling varying inlet pressures
  • Inlet sizes: 1¼" F NPT, 1¼" F BSP Outlet sizes: 1" F NPT, 1¼" F NPT, 1" F BSP, 1¼" F BSP
  • Very low hysteresis and friction losses
  • Maximum flow path resists plugging
  • Patented design
  • 100% water-tested for accuracy (no adjustments ever needed)
  • One-year warranty on materials and workmanship

One regulator can handle multiple lines as long as their combined flow does not exceed that of the regulator.

When the flow exceeds the capacity of a single regulator, you may use two or more regulators in parallel to achieve the same result.

Be sure to install the regulator in the proper direction. The arrow on the side of the lower housing shows the direction of flow and should always point downstream.
