Typical Applications

Automatic Refreshing of Reservoirs This valve is installed as a short cut between the reservoir supply line and the pump discharge line to the distribution system. The Model 710-20 presents three major advantages:

  • Saving energy and expensive pumping hours when supply pressure is sufficient
  • Enabling automatic refreshing of water in the reservoir
  • Ensuring uninterrupted supply during reservoir maintenance
