Belimo Actuator for Globe Valve 20mm Stroke 24VAC/DC 1000N BACnet/Modbus IP40 150s VNV24A-LP1

This Belimo linear electrical actuator is designed for controlling globe valves. The stroke length is 20 mm. The actuator delivers a force of 1000 N and can open/close the valve in 150 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 actuator features BACnet IP/Modbus TCP control, enabling versatile communication and interoperability with other systems for streamlined control and monitoring capabilities. The actuator has a durable plastic housing and has an IP40 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 push-button, which disengages the gear train for as long as the button is pressed or locked. The stroke can be adjusted using a 4mm hexagon socket screw key inserted at the actuator's top, with the stroke shaft extending when turned clockwise. Manual triggering of adaptation can be done by pressing the "Adaptation" button. Both mechanical end stops are detected during the adaptation (entire setting range). The actuator then moves into the position defined by the control signal. The actuator can be directly mounted on the globe valve using form-fit hollow clamping jaws and it can be rotated 360° on the valve neck. The actuator is controlled via the Cloud, BACnet IP, or Modbus TCP and moves to the position defined by the control signal. Various data points can be written and read via the same interfaces. In hybrid mode, the actuator receives its analog control signal from the higher-level controller and moves to the defined position. Various data points can be read and written (except for the control signal) using the Cloud, BACnet IP, or Modbus TCP.

Pros:

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

Cons:

• The time to open/close of 150 s is slow for some applications
