Thermoelectric actuator for individual control of heating circuits on an underfloor heating manifold – this is especially important with multiple loops controlling different heating zones.
The valve contains a wax element, which on receipt of a signal from the thermostat (normally via a wiring control box), the valve will open, allowing the warm water to flow through the relevant pipework loop. The actuator valves are fixed onto the manifold beam with a M30 nut (part of the valve).
