Honeywell Home V4043H1056 22mm Two-Port Zone Valve
The Honeywell Home V4043H1056 is a normally closed, two-port motorised zone valve with 22mm compression connections for controlling flow to a heating circuit.
- Action: Motor opens the valve; spring return closes it when power is removed
- Auxiliary end switch: Potential-free SPST end switch for electrical control of a pump and/or boiler
- Manual lever: For system filling and draining
- Flow coefficient (Kv): 6.9
- Maximum close-off differential pressure: 0.55 bar
Match the exact valve model and heating-system controls before ordering. Powerhead servicing depends on the actual valve-body generation and any adaptor; do not assume every version can be serviced without draining.
Check Resideo’s replacement-powerhead instructions against the actual head and body. Installation and servicing must follow the manufacturer’s instructions.
