Honeywell V4043H 1056 22mm 2-Port Motorised Zone Valve 240v Closed with Aux Switch Overview

The Honeywell V4043H motorised valve helps control the flow of water in domestic central heating control systems, where both radiator and hot water cylinder circuits are pumped. Normally, closed models have end switches for electrical control of pump and/or boiler, whereas the Honeywell V4043B is particularly applicable to control of solid fuel systems, since it will always continue operating in the event of a power failure.
