The Belimo EVC24A-MF-REis a kind of Actuator used to operate valves in HVAC applications and systems.

The force applied by the Torque of the EVC24A-MF-RE is 2500 N.

This Valve Actuator needs to be supported by a power supply of 24Vac/Vdc.

This Belimo component can be used with Globe Valves.

If you have questions concerning size or installation, refer to the Belimo custom datasheet above or email iacs for individualised support.

EVC24A-MF-RE Globe Valve Actuator, AC/DC 24 V, 35 s

• Globe valve actuator retrofit
• 2500 N, 50 mm
• AC/DC 24 V, modulating, multifunctional
• Actuating time motor 35 s / 40 mm
• Operating range DC 2...10 V, adj.
• Position feedback DC 2...10 V, adj.
• IP54, manual override temporary, perm.
• Universal valve adapter enclosed
• Connection cable PVC 1 m

Mode of operation: The actuator is connected with a standard modulating signal of DC 0 ... 10V and travels to the position defined by the positioning signal. The measuring voltage U serves for the electrical display of the actuator position 0 ... 100% and as slave control signal for other actuators.

Parameterisable actuators: The factory settings cover the most common applications. Input and output signals and other parameters can be altered with the PC-Tool MFT-P or with the Service tool ZTH EU.

Installation on third-party valves: The retrofit actuators for installation on a wide range of valves from various manufacturers are comprised of an actuator, universal valve neck adapter and universal valve stem adapter. Adapt the valve neck and valve stem to begin with, then attach the retrofit actuator to the valve neck adapter, connect to the valve and start up. The valve neck adapter/actuator can be rotated through 360° on the valve neck, provided it is permitted by the size of the installed valve.

Installation on BELIMO valves: Please use standard actuators from Belimo for installation on Belimo globe valves. The installation of retrofit actuators on Belimo globe valves is technically possible.

Manual override: Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked). The stroke can be adjusted by using a hexagon socket screw key (5 mm), which is inserted into the top of the actuator. The stroke spindle extends when the key is rotated clockwise.

High functional reliability: The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.

Position indication: The stroke is indicated mechanically on the bracket with tabs. The stroke range adjusts itself automatically during operation.

Home position: Factory setting: Actuator spindle is retracted. The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out an adaption, which is when the operating range and position feedback adjust themselves to the mechanical setting range. The actuator then moves into the position defined by the positioning signal.

Direction of stroke switch: When actuated, the direction of stroke switch changes the running direction in normal operation.

Adaption and synchronisation: An adaption can be triggered manually by pressing the „Adaption“ button or with the PC-Tool. Both mechanical end stops are detected during the adaption (entire setting range). Automatic synchronisation after pressing the gearbox disengagement button is configured. The synchronisation is in the home position (0%). The actuator then moves into the position defined by the positioning signal. A range of settings can be adapted using the PC-Tool (see MFT-P documentation)
