Belimo Retrofit Globe Valve Actuator 0-10/2-10V 20mm Stroke 24VAC/DC 1500N 35s IP54 MP-Bus Terminals SVC24A-MP-RE
This Belimo retrofit linear electrical actuator is designed for controlling globe valves. The stroke length is 20 mm. The actuator delivers a force of 1500 N 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 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 has a durable plastic housing and has an IP54 protection rating. This actuator can operate within ambient temperatures between 0 and 50 °C (32 and 122 °F). The actuator comes with a 1-meter power cable.

Description
This Belimo retrofit linear electrical actuator is designed for controlling globe valves. The stroke length is 20 mm. The actuator delivers a force of 1500 N 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 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 has a durable plastic housing and has an IP54 protection rating. This actuator can operate within ambient temperatures between 0 and 50 °C (32 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. 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 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 default factory setting retracts the actuator stem.
Pros:
- Modulating actuator with a control signal of 0-10 V/2-10 V
- Manual override
- The actuator is overload protected
- Visual position indicator
Cons:
- The time to open/close of 35 s is slow for some applications
