Hanicks 2 Port Motorised Zone Valve Actuator Head – Compatible Replacement The Hanicks 2 Port Motorised Zone Valve Actuator Head is a compatible replacement designed for use with selected 22mm and 28mm 2 port motorised heating zone valves. Engineered for reliable performance in domestic central heating systems, this 5 wire actuator head is suitable as a replacement for Honeywell 40003916-001 and fits applications commonly associated with V4043H1056 and 272848 style valve systems. A zone valve actuator controls the flow of heated water through different heating zones within a central heating system. When an actuator becomes faulty it can cause issues such as heating remaining on continuously, heating failing to activate correctly, or the valve not responding to the thermostat or programmer. The Hanicks compatible actuator motor is designed to restore reliable heating control. With its 5 wire configuration and normally closed spring return operation, the actuator opens when power is applied and automatically closes when power is removed to ensure safe heating system operation. The integrated manual override lever allows the valve to be opened manually for system filling, draining, or testing, making servicing easier for installers and heating engineers.
