D146 Differential Pressure Regulators
Used to eliminate excessive pump head pressure when most radiator valves are closed due to reduced demand.
• 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.
