This Honeywell twin pack contains two 2 port motorised zone valves, each with a 22mm connection, suitable for controlling water flow in domestic or light commercial central heating systems. Each valve features a normally closed design and is equipped with an end switch to support electrical control of system pumps and boilers.
On site, these zone valves are typically installed to divide heating circuits, enabling independent operation for areas such as heating zones or hot water cylinders. The 22mm compression fittings make these valves compatible with standard pipework, streamlining installation for plumbing and heating engineers.
