Electrothermal valve actuators for heating, ventilation and air conditioning technology. The drive is very space-saving thanks to its compact design. The tapered design, especially in the fastening area of the nut, makes installation easy. The fastening cable is not in the area of the fastening nut. This reduces the likelihood of contact with devices carrying hot water. Since the fastening nut allows continuous screwing onto the thread, unlike bayonet and snap couplings, the valve can be opened in a de-energized state by turning the nut back two to three threads. Leaking water is drained away via a drainage system. Thanks to a special design, seals were not required. The current valve position is displayed in 2 positions (top and side). Due to their M 30 x 1.5 fastening and their characteristics (normally closed), the actuators are suitable for the following valve and distributor brands, among others: Beulco, Empur, Heimeier, Kamo, Oventrop, Purmo, SBK, SKV, Strawa, Taconova, Watts.
