Piping
The valves should be mounted in a weather-protected area in a location that is within
the ambient limits of the actuator. Allow sufficient room for valve with actuator and for
service. Please allow 12” for complete actuator/linkage removal. The G6/G7 preferred
mounting position of the valve is with the valve stem vertical above the valve body,
for maximum life. However, the assemblies can be mounted with valve stem vertical
above the valve or up to 45 degrees in relation to the horizontal pipe. The actuators
should never be mounted underneath the valve, as condensation can build up and
result in a failure of the actuators. Do not reverse flow direction.

EVX24-MFT
Proportional, Non-Spring Return, Linear, 24 V, Multi-Function Technology®
Application
For multiple control types of globe valves in HVAC steam and hydronic systems.
Actuator sizing will be dictated by the valve size selection. All valve selections should
be done in accordance with the flow parameters and system specifications. The
actuator is mounted directly to the globe valve bonnet by means of its universal clamp
and collar.
The actuator operates in response to many controls types as desired by the customer
and/or design control input from an electronic controller or positioner. A 2 to 10 VDC
feedback signal is provided for position indication.
Operation
The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The EV series provides 50 mm of downward
travel and a visual indicator indicates position of the actuator. When reaching the valve
end position, the actuator automatically stops. The gears can be manually disengaged
with a button on the actuator cover.

Add-on auxiliary switches are easily fastened directly onto the actuator body for
signaling and switching functions.
-SR and –MFT models will have an illuminated green Adaption/Power button to reset
and relearn the valve stroke as well as indicate the actuator is powered. This feature
allows the actuator to rescale itself based on the actual travel. Along with the Adaption
button on –MFT models will have a yellow Status light to confirm communication.

† Use flexible metal conduit. Push the Listed conduit fitting device over the actuator’s cable to butt against
the enclosure. Screw in conduit connector. Jacket the actuators input wiring with Listed flexible conduit.
Properly terminate the conduit in a suitable junction box. Rated impulse Voltage 800V. Type of action 1.

Technical Data
The EV… series actuators use a sensorless brushless DC motor. The ASIC inside
monitors and controls the actuator’s rotation and provides a digital rotation sensing
(DRS) function to prevent damage to the actuator in a stall condition. Power
consumption is reduced in holding mode.

Typical Specification
24 VAC Transformer
Proportional control globe valve actuators shall be electronic and direct coupled to the
globe valve bonnet via an integrated linkage, which requires no secondary linkage and
be capable of mounting to valves 2.5” to 6” in size. Actuators must provide control in
response to a control input from an electronic controller or positioner. Actuators shall
have brushless DC motor technology and be protected from overload at all angles of
rotation. Actuators shall have reversing switch and manual override on the cover. Run
time shall be constant and independent of torque. Actuators shall be cULus listed,
have a 5-year warranty, and be manufactured under ISO 9001 International Quality
Control Standards. Actuators shall be as manufactured by Belimo.
