Manual Automatic Valve Actuator 24v Underfloor Heating Systems DN20
Electric valve actuators control the opening and closing of valves. They can provide linear or rotary motion and work with different types of valves, including ball valves and butterfly valves.
- Compact and economical
- Can make the valve power off when fully open or closed.
- Three installation types: Nut mounting, vertical press way, snap-assembly

Installation notes
Before any service work on the final controlling device is carried out, it is essential to isolate the rotary actuator from the power supply (by unplugging the electrical cable if necessary). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow all components to cool down first if necessary and allows to reduce the system pressure to ambient pressure level).
The system must not be returned to service until the ball valve and the rotary actuator have been correctly reassembled in accordance with the instructions and the pipeline has been refilled by professionally trained personnel.
