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.
