Differential Pressure Regulator - 19992

19992 MFG #: D146M1040
0.00000 /

The differential pressure regulator eliminates excessive pump head pressure, when most radiator valves are closed due to reduced demand, by controling flow through a bypass line when the difference between supply/return exceeds the setpoint.

  • Features
  • Specifications
    • Diaphragm of EPDM.
    • Brass valve body with thermoplastic and stainless steel parts.
    • Built-in differential pressure indicator.
    • Easy adjustment of pressure by turning regulating cap.
    • Easy installation; requires no electrical hookup.
    • Provides silent, trouble-free service.
    • Control maintains a constant differential between the two sides by opening a bypass whenever the difference between supply and return reaches the setpoint.
    • Install between supply and return sides of a hydronic system to stabilize pressure differential and reduce the effects of demand changes.
