Belimo Actuator 2&3-Point 100-240VAC 10Nm IP54 90s NR230A

This Belimo electrical actuator is designed for controlling quarter turn valves. The actuator delivers a torque of 10 Nm and can open/close the valve in 90 seconds. This actuator requires a supply voltage of 100-240 V AC and has a visual positioning indicator to clearly see the valve position. The actuator features two-point and three-point control. 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:

• Manual override
• The actuator is overload protected
• Visual position indicator

Cons:

• The time to open/close of 90 s is slow for some applications
