The V4043H motorized zone valve can be used to control the flow of water in iron and copper pipe systems. Although it is specifically designed for small bore central heating systems, the valve can be used in commercial and industrial applications.
The V4043H motorised zone valve is designed to control water flow in iron and copper pipe systems, primarily for small‑bore central heating but also suitable for commercial and industrial applications. It operates on 220‑240V AC and includes a manual lever for AUTO or MAN OPEN positions.
The guide provides detailed installation steps, including required Class A switching, wiring to a Honeywell junction box, proper plumbing practices, and a checkout procedure to verify heating and hot‑water functions. Safety notes stress competent installation and compliance with I.E.E. and Electricity at Work regulations.
