The Honeywell Home DU145 22mm Angled Automatic Bypass Valve (DU145-3/4B) is designed to maintain consistent differential pressure and minimum water flow within central heating systems. By automatically regulating bypass flow as heating demand changes, it helps maintain boiler circulation, reduce unwanted system noise and support efficient heating system operation.

Manufactured from durable brass, the DU145 features an angled body design with 22mm compression connections for straightforward installation. It offers an adjustable differential pressure range of 0.1–0.6 bar and a high flow capacity of up to 50 litres per minute.

The valve is particularly useful in systems where thermostatic radiator valves or other control valves close, helping maintain circulation and reduce flow noise as system pressure changes.
