Belimo Actuator 2-10V 24VAC/DC 2Nm IP54 75s KR24-SR

This Belimo electrical actuator is designed for controlling quarter turn valves. The actuator delivers a torque of 2 Nm and can open/close the valve in 75 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 with a magnet, which disengages the gear train as long as the magnet sticks to the magnet symbol. A Z-MA magnet for gear train disengagement is included. 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 actuator can be adjusted from 90° (A-AB = 100%) in increments of 2.5°. The scale represents 25-100% of the kvs value. The actuator links with a standard 2-10 V control signal and moves to the position outlined by the control signal. Voltage measurement is employed both for visually displaying the valve position within the 0.5% to 100% range and as a control signal for other actuators. 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 75 s is slow for some applications
