Differential Pressure Regulator

Differential Pressure Regulator

  • Product Info
  • Literature

Overview

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

  • 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.
