SEH35 thermal actuator is mainly used in hydronic floor heating system. As an important part in the manifolds, its function is to open or close each circuit in the flow manifold. The actuator is connected with room thermostats. When the indoor temperature reaches to the setting temperature, the actuator, driven by the inside wax motor, closes the port of each circuit in the flow manifold and stops the heating water flowing from the heating source to pipes. When the indoor temperature decreases, the actuator opens the port and allow warm water to flow through each circuit.
It’s connection size is universal type M30*1.5, suitable for many different brands of manifolds. There are 3mm and 5mm strokes available, and voltage 230V and 24V for choice, meeting customers various demands.
-Wax-filled element, driven by heated PTC
