On/Off, PWM & 0-10 VDC Globe Valve Actuators
Specifications subject to change without notice. | USA 110526 | Page 1 of 4
DESCRIPTION
MVX / MVR
Electro-thermal, bidirectional, zone globe valve actuators with normallyopen or normally-closed fail-safe control providing completely silent,
maintenance-free operation. Available with on/off, pulse width modulation
(PWM) or 0-10 VDC modulating control signal input. Compatible with
VSX (2-way) and VMX (3-way) ½” and ¾” zone globe valve bodies.
APPLICATION
For the actuation of chilled and hot water valves on fan coil units, reheating
of variable air volume (VAV) or variable volume & temperature (VVT) boxes,
base boards, and other A/C units. The silent operation and dampened
response of these electro-thermal actuators make them superior for spaces
with low ambient noise and gradual heating/cooling load changes.

Actuator will be damaged if 110...230 VAC is applied to
the 24 VAC actuator.
Be patient; it may take several minutes to stroke 100%

MANUAL OVERRIDE
COUPLING TO THE VALVE BODY
VXC-CAP
Ensure the actuator piston/stem is lined up with the actuator
mounting neck. Screw
the actuator’s knurled
ring nut (M30 x 1.5 mm)
onto the threaded neck
portion of the valve body
by hand only.
Manual override cap
Screw the override cap
onto the threaded neck
portion of the valve body,
and stroke down the
valve stem into any partial
or fully open position.
