Description
Used to eliminate excessive pump head pressure when most radiator valves are closed due to reduced demand.
  • Install between supply and return sides of a hydronic system to stabilize pressure differential and reduce the effects of demand changes.
  • Control maintains a constant differential between the two sides by opening a bypass whenever the difference between supply and return reaches the setpoint.
  • Provides silent, trouble-free service.
  • Easy installation; requires no electrical hookup.
  • Easy adjustment of pressure by turning regulating cap.
  • Built-in differential pressure indicator.
  • Brass valve body with thermoplastic and stainless steel parts.
  • Diaphragm of EPDM.
