Danfoss, Heating Solutions: Pressure-Independent Control Valve ActuatorThe new generation of 435 Series actuators will replace the prior AME 15QM Series of actuator for the AB-QM pressure-independent control valve (PICV). The AME 435QM and AMV 435 are the first of a new design of actuators, the company said. The actuators require no additional tools when they are installed to the AB-QM valve bodies. The click-on mounting mechanism of the actuator reduces actuator installation time, said the company. Standard features include two selectable operation speeds, external LED for visual confirmation of actuator operation, end-travel LED signaling, and easy calibration via an external reset button. The 435 Series is smaller and lighter than the previous model with 24-vac or -vdc power capabilities. When a Logarithmic or equal percentage setting is selected, an optional adjustment can be made to the equal percentage characteristic, effectively matching the actuator to the coil, leading to an efficient control and balancing by the AB-QM assembly.
