TWA
TWA 是一款用于电气开/关控制的小型执行器,设计用于操作各种类型的阀门和地板采暖歧管。
TWA 系列产品包括适用于 24 V (SELV*) 或 230 V 电源的执行器,有常闭 (NC) 和常开 (NO) 两种版本(阀门位置,执行器无供电电压)。
对于某些类型的执行器,也可提供带限位开关的 NC/S 版本。
每个执行器都配有可视位置指示器,以显示阀门是打开还是关闭。
TWA 可连接至丹佛斯的 RA、RAVL 和 RAV 阀门。TWA-K 版本(M30×1.5)可连接至 Heimeier、MNG 和 Oventrop 阀门。
其他阀门必须逐一进行验证,以确保阀门关闭尺寸和阀门顶部几何形状正确。

ABN-FBH
The ABN-FBH actuator is a thermal wax actuator (TWA) for opening and closing valves on heating circuit manifolds in underfloor heating systems. The actuator has been specially developed for targeted use in the widest variety of systems. Its compact size, design, functionality and flexibility are the most impressive features. A valve adapter concept guarantees the perfect adjustment of the actuator to almost any valve bases and heating circuit manifolds on the market.
The ABN-FBH actuator serves to ensure the optimum control of valves on heating circuit manifolds. Control can be implemented using ON/OFF switching or by applying pulse‑width modulation (PWM).
The ABN-FBH range includes actuators for 24 V (SELV*) (*SELV = Safety Extra Low Voltage) or 230 V supply.
Actuator ABNM A5 LOG/LIN
The ABNM A5 0-10V thermal actuator has beenspecifically designed for use with AB-QM valvesDN10-32/½-1¾ inch in heating and coolingapplications.
Control is done by a 0-10 V signal, which is provided either by a room thermostat or, in most cases, by a central direct digital control(DDC) system. The actuator converts the 0-10 V signal into a proportional actuator travel, which logarithmic / equal percentage (ABNM A5 LOG).For fan coil unit or chilled ceiling application choice of logarithmic version is recommended (water to air heat exchanger). The result will belinear system response and thus optimal room temperature control.
