SEH35 Thermostatic Actuator for Underfloor Heating SEH35 Thermostatic Actuator for Underfloor Heating

SEH35 Thermostatic Actuator for Underfloor Heating
MENRED SEH35 thermostatic actuator apply to temperature control, fluid mixing center and freeze protection, as a valve and manifolds actuator to open or close based on a temperature set point. SEH35 thermal actuator is available to 24V and 230V, wax-based makes the actuator performance better, that result actuator as a star product of menred, with annual sales of over million.

Description



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.

FAQs

what is a motorized valve in HVAC? what is a motorized valve in HVAC?
Menred motorized valves are for heating and cooling(Fan coil unit), to ensure stable and accurate control room temperature. Electric motor is mounted on the valve and geared to the valve stem to open or close the valve.

how do underfloor heating actuators work? how do underfloor heating actuators work?
Underfloor heating actuator is controlled by room thermostat, it open or closed according to room temperature or manifolds loops return water temperature. The electric heating actuator realises the temperature adjustment function through the principle of thermal expansion and contraction of the temperature sensing element. It is mainly used in the room temperature control or layered temperature control system of the floor heating system. In the individual room where the UFH is installed, the temperature needs to be adjusted, and the temperature controller can be set Linked with thermal actuator.

What does a thermal actuator do? What does a thermal actuator do?
Thermal actuator is the key component of underfloor heating system, it works with manifolds to open or close a valve based on a temperature setting value. It design to replace manual balancing valve on manifolds to provide electronic control of each individual manifolds branch.
