Belimo Actuator 2-10V 24VAC/DC 2Nm IP40 35s TRY24-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 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 IP40 protection rating. This actuator can operate within ambient temperatures between -7 and 50 °C (19 and 122 °F). The actuator comes with a 1-meter power cable.

To manually change the position, press and hold the override button, then turn the lever. The actuator has overload protection and automatically stops upon reaching the end stop. In case of blockage, the actuator switches off for seven seconds before attempting to restart. If the blockage persists, the actuator attempts to restart 15 times every two minutes and subsequently only once every two hours. 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 controlled with a standard control signal of 2-10 V and moves to the position dictated 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
• Visual position indicator

Cons:

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