Belimo Actuator 0-10/2-10V Fail-Safe NO 24VAC/DC 4Nm IP54 75s LRF24-MP-O
This Belimo electrical actuator is designed for controlling quarter turn valves. The actuator delivers a torque of 4 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 actuator utilizes the MP-Bus communication protocol and provides position feedback in the range of 0-10 V or 2-10 V, allowing for precise control and accurate monitoring of its position within the specified voltage range. The actuator simultaneously positions the valve for operation while tensioning the return spring. If the supply voltage is cut off, the spring force returns the valve to its open position. 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.

Description
This Belimo electrical actuator is designed for controlling quarter turn valves. The actuator delivers a torque of 4 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 actuator utilizes the MP-Bus communication protocol and provides position feedback in the range of 0-10 V or 2-10 V, allowing for precise control and accurate monitoring of its position within the specified voltage range. The actuator simultaneously positions the valve for operation while tensioning the return spring. If the supply voltage is cut off, the spring force returns the valve to its open position. 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. The valve can be manually operated and adjusted to any position using a hand crank. Unlocking can be done manually or automatically by applying the operating voltage. 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 connects with a 0-10 V control signal and moves to the position defined by the 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. In bus operation, the actuator receives its digital control signal from the upper-level controller via the MP-Bus and moves to the defined position. The U connection serves as a communication interface without providing an analog measuring voltage. The rotation angle can be adjusted with mechanical end stops.
Pros:
- The actuator is equipped with a fail-safe feature
- Modulating actuator with a control signal of 0-10 V/2-10 V
- The actuator is overload protected
- Visual position indicator
Cons:
- The time to open/close of 75 s is slow for some applications
