The Honeywell Home DU144 22mm Straight Automatic Bypass Valve (DU144A1001) is designed for central heating systems to maintain a minimum flow rate through the boiler and help regulate system pressure. By automatically adjusting the bypass flow in response to changes in system demand, it helps maintain hydraulic balance and reduce unwanted noise within the heating circuit.

Manufactured from durable brass, this straight-pattern automatic bypass valve features 22mm compression connections and an adjustable differential pressure range of 0.1–0.6 bar. It is factory-set at 0.2 bar, with a lockable pressure setting to help prevent accidental adjustments once correctly commissioned.

The DU144 provides a practical solution for domestic central heating installations where a controlled bypass circuit is required.
