The differential pressure regulator from Resideo 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.

• 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.
