Belimo Actuator 2-10V 24VAC/DC 20Nm IP54 35s SRC24A-SR

This Belimo electrical actuator is designed for controlling quarter turn valves. The actuator delivers a torque of 20 Nm and can open/close the valve in 35 seconds. This actuator requires a supply voltage of 24 V AC/DC and has a visual positioning indicator to clearly see the valve position. The modulating actuator is requires a 2-10 V input and offers position feedback, ensuring precise control over its operation and accurate monitoring of its position within the designated voltage range. The actuator has a durable plastic housing and has an IP54 protection rating. This actuator can operate within ambient temperatures between -30 and 50 °C (-22 and 122 °F). The actuator comes with a 1-meter power cable.

The actuator is equipped with overload protection, the actuator doesn't need limit switches and will stop automatically when the end stop is reached. Manual override is possible using a push-button, which disengages the gear train as long as the button is pressed or remains locked. The actuator can be directly mounted on the ball valve using a single screw. The mounting orientation relative to the ball valve can be chosen in 90° increments. The rotation angle can be adjusted with mechanical end stops.

Pros:

• Modulating actuator with a control signal of 2-10 V
• Manual override
• The actuator is overload protected
• Visual position indicator

Cons:

• The time to open/close of 35 s is slow for some applications
