Electrothermal valve actuators for heating, ventilation and air conditioning technology
Technical data
Application
Housing colour: Housing material:
pure white, like RAL 9010
Extremely compact design: Can be fitted quickly and comfortably thanks to the slim shape in the area around the fastening nut. Can be fitted in any position: Lateral drainage holes carry off any leakage water that from the valve plunger into the open, thus avoiding damage to the drive. Additional valve monitoring: Two additional viewing windows at the side allow users to visually check the respective valve position with ease; this does not work when mounted in a suspended manner.

Thanks to their M 30 x 1.5 fastening and their characteristics (normally closed), the actuators are suitable for the following valve and distributor makes: Beulco, Empur, Heimeier, Kamo, Oventrop, Purmo, SBK, SKV, Strawa, Taconova, Watts Brief description : The drive features a compact, space-saving design. The device can be mounted easily thanks to the narrowed shape, especially in the fastening area of the nut. The fastening cable is not located near the fastening nut. This reduces the probability of contact with equipment carrying hot water. Since the fastening nut allows continuous screwing onto the thread, by unscrewing the nut by two or three turns, it is possible to open the valve in an electrically de-energised state – something that cannot be done with bayonet couplings and impulse couplings.
Discharged water is dissipated via a draining system. Gaskets are not required thanks to the careful design.
The double position display has the following advantages : The upper display provides the option of a visual or, in conditions of bad visibility, tactile function test of the drive.
The lower viewing windows allow an additional check to determine whether the valve to be actuated follows the lifting movement of the drive. At the beginning of the heating period, it can happen off and on that the valve plungers get “stuck”. Therefore, with the additional display, it is possible to determine whether the cause lies with the actuator or with the valve in the event the valve does not open. However, that is not possible when mount- ed in a suspended manner.
