Our actuators are mounted with nut (30x1.5mm),which can be manually rotated to install without the use of additional tool,making installation and removal very convenient. It mainly used in floor heating systems in the Radiants Heat Manifold,radiator,water to air heat exchyanhger. The use of electrothermal actuator can effectively adjust the water flows of floor heating supply and return pipe to achieve the purpose of energy saving and efficiency enhancement. The actuator is connectting to the thermostat for use,according to the set temperature automation management pipelines opening and closing,maintain room temperature. Adopts semiconductor heating ceramics,which can heat up quickly,control room temperature accurately,and enhances the comfort of your home.
