The Honeywell 22mm 3-way mid-position valve is an industry-standard motorised component designed for precise hydraulic diversion in domestic Y-plan central heating systems. Engineered to direct the flow of hot water from the boiler to either the radiator circuit, the hot water cylinder, or both simultaneously, it ensures optimal thermal management across the property. The valve features 22mm compression fittings, allowing for robust and leak-free integration directly into existing copper pipework.

Weighing 1.28kg, the unit incorporates a reliable hardwired actuator that responds rapidly to signals from room thermostats and cylinder stats. The renowned Honeywell Home engineering ensures smooth, quiet operation without causing pipework hammering or flow restriction. Built to handle standard domestic system pressures and high temperatures, this mid-position valve is a trusted replacement part utilised by heating professionals for its exceptional longevity and fault-free performance.
