Belimo Globe Valve Actuator 3-Point 5.5mm Stroke 24VAC 400N 35s IP40 Siemens NRYD24-3-SI

This Belimo linear electrical actuator is designed for controlling globe valves. The stroke length is 5.5 mm. The actuator delivers a force of 400 N and can open/close the valve in 35 seconds. This actuator requires a supply voltage of 24 V AC and has a visual positioning indicator to clearly see the valve position. The actuator features three-point (open-close) control. The actuator has a durable plastic housing and has an IP40 protection rating. This actuator can operate within ambient temperatures between 0 and 50 °C (32 and 122 °F). This actuator is compatible with valves. 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.

Pros:

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

Cons:

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