The Horstmann family of ZonePlus motorised zone and diverter valves has been completely upgraded to combine proven electronic controls technology with high quality manufacture and the latest Horstmann design features.
With the ZonePlus Z series, the aim is to make reliability the watchword for these products with mechanisms featuring high quality components and the actuation provided by the proven and reliable Hansen synchron motor.
There are three valves in the new range - model Z222 and model Z228 are 22mm and 28mm 2 port spring return valves and model Z322 is a 22mm 3 port mid position diverter valve.
The Z222 with auxiliary switch has been designed to control the water circulation in fully pumped systems, which employ a single pump for both hot water and central heating circuits by allowing the flow to either or both circuits using separate valves.
The Z228 with changeover auxiliary switch has been designed to control the water circulation in both gravity HW systems and larger fully pumped systems, which employ a single pump by allowing the flow to either or both HW and CH circuits using either a single or separate valves.
The Z322 mid-position valve has been designed to control the water circulation in fully pumped systems, which employ a single pump for both hot water and central heating circuits by diverting the flow to either or both simultaneously using a single valve.
The valves are all supplied with a 1.4m electrical connection cable to accommodate easier installation in inaccessible areas, compression fittings and a removable quick change actuator. They are also covered by a two year guarantee.
