Honeywell V4043H 1056 2 Port Zone Valve Normally Closed 22mm

This 22mm Honeywell V4043H 1056 is a two-port motorised zone valve designed to be normally closed, featuring end switches that enable precise electrical control of both pump and boiler. It operates with a motor to open and uses a spring for return action, while a manual lever allows system filling and draining. The powerhead can be replaced without the need to drain the system, and a potential-free end switch supports additional electrical controls. It ensures quiet operation with low power consumption, making it a reliable choice for zone control in heating systems.
