Description
Reliable actuator for water-side valves
The Belimo SRF24A-MOD water-side actuator with Safety function is specially designed for motorized positioning of control ball valves, zone valves, or mixing valves in heating and cooling installations. The actuator combines normal valve operation with a defined safety position in the event of a power failure. With a Torque of 20 Nm, the Execution is matched to a suitable valve size and mechanical load.
This actuator, together with a compatible water-side valve, forms one control assembly. Torque, running time, supply voltage, and management are matched to the valve series and the desired control function.
