What it is
The Esi 2 Port Metal Actuator Head is a replacement actuator for ESI Controls 2 port motorised valves. It controls the flow of water in central heating systems by opening and closing the valve in response to a thermostat or programmer signal. This metal-headed actuator is designed for boiler applications.
Signs this part needs replacing
