Product Description
Honeywell D146M1040 11/4" Differential Pressure RegulatorOverview
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.
