The series of SAS31, SAS61 and SAS81 SIEMENS actuators is a series of electromechanical actuators with a stroke of 5,5 mm and a force of 400 N offered by Siemens. They are designed to control the two-way and three-way Siemens V..G44, VVG55 and VVG549 valves used as control or shut-off valves in heating and air-conditioning installations. Using the ASK30 mounting adapter, they can also be used with the former Landis & Gyr valves with a 4 mm or 5,5 mm stroke type: X3i, VVG45, VXG45, VXG46 and VVI51.
