ESI 3 port zone valve

Reward points0

The ESi Controls 3 port motorised zone valves are easy-fit, with a simple clip on/off detachable actuator head and detachable cable. The actuator has been designed to fit directly onto the valve body used by the market leader, and similar type bodies, with the two supplied screws – making it a quick-fit direct replacement for most households.


The spring return valves have been designed to be used in light commercial, industrial and domestic central heating systems which, when correctly wired with an appropriate room thermostat, cylinder thermostat and programmer, will control the water flow from the boiler to hot water, and from the boiler to ‘central heating’.
