Product at a glance

Z222 is a 2-port, 22mm motorised valve that combines proven controls technology with the latest design features, for easy installation and maintenance. It has an auxiliary switch to control the water circulation in fully pumped systems that have a single pump for both hot water and central heating circuits, by controlling the flow to either or both circuits, through separate valves. The valve is supplied with a 1.4 m electrical connection cable, for easy installation in inaccessible areas, compression fittings and a removable quick-change actuator. It is covered by a 2-year guarantee. There are three models in our range of valves: 22 mm and 28 mm 2-port spring-return valves, and a 22 mm 3-port mid-position diverter valve.


Heating zone flow control ZonePlus Z222 is designed to control flow to a zone within a central heating system.
