·

SSC61.5

same as SSC61, plus electrical fail-safe function

·

Nominal force 300 N

·

Automatic identification of valve stroke

·

Direct mounting with coupling nut, no tools required

·

Cable connection via screw terminals

·

Manual override with indication of position and direction of travel

·

Parallel connection of multiple actuators

Use

For operation of Siemens valves of the V..P45.. range

for water-side control of hot and

cooling water in heating, ventilation and air conditioning systems

.

In conjunction with the ASK30 mounting kit, the former Landis & Gyr valves VVG45..,
VXG45.. and X3i.. can also be operated.
