Multi-Fit 230v Four 4 Wire Thermal Actuator For Radiant Floor Heating 24V
Electric Thermal Actuator DR-10
Product Description:
Electric thermal valve actuators are used for opening and closing valves and small valves on heating circuit distributors of surface heating and cooling systems. The predominent area of application is the enery efficient room-by-room temperature control in the area of building services and automation.
Electrothermal actuators are mainly used in underfloor heating systems to control the closing and opening of pipes through the manifolds valves. It is specifically used in the electric drive part of the electrothermal actuator of the manifold branch valve, small valve and dynamic balance valve. The working operation is noise-free, and the nut connection and installation method is simple, quick to install, and easy to disassemble.
Working Principle:
Electrothermal actuator consists of three parts: temperature controller, valve actuator and valve. The room thermostat is installed on the inner wall of the room, and is connected to the electric heating actuator with a cable or without cable(wireless also available). Generally, a 75cm long cable is used to connect the actuator to the selected control point (thermostat, programmer, timer or other remote control device). The actuator is attached to the valve with a nut. When the indoor temperature reaches the temperature set by the temperature controller, the positive thermistor in the electric heating actuator starts to work, heating the thermal expansion device to close the valve, otherwise, the indoor temperature decreases, the thermostat is disconnected, the actuator cools down, and the expansion device shrinks , the valve opens. Generally, it has the function of automatic reset after power failure.
Features:
1. Overvoltage protection guarantee.
2. Simple slot assembly.
3. Compact design.
4. Fixed connection cable.
5. Superior reliability with long service life expected.
6. Available as a normally closed (NC) or normally open (NO) version.
