M5004-24V electromotive actuators are used in many kinds of
control systems employed in HVAC applications, including
ON/OFF, floating, proportional managed by thermostat or
BMS handling analog signals.
The V5004TF valve is designed to maintain a constant set
flow in spite of fluctuations in the pressure-drop.
Always protect the pressure regulator by using strainers
upstream of the valve and, in any case, make sure water
quality complies with VDI 2035 standards (Fe < 0.5 mg/kg
and Cu < 0.1 mg/kg).
Furthermore, the concentration of iron oxide in the water
passing through control valve (PICV) should not exceed 25
mg/kg (25 ppm).
To ensure the main pipework is cleaned appropriately,
flushing bypasses should be used without flushing through
the valve's pressure regulator, thereby preventing clogging.

1. Mount the valve with the arrow in the direction of
Mounting the valve in the wrong direction may
damage the system and the valve itself.
If flow reversal is possible, a non-return valve should be
2. Observe Proper Orientation of the Valve!
The stem must be above the horizontal.
3. Avoid Mechanical Stress!
When mounting the valve, do not subject it to any undue
mechanical stress or strain! It is especially important that no
torque be applied to the actuator during mounting.
4. Operating Control
To ensure that the valve is working in its operating differential
pressure range, measure the differential pressure across the
Provided that the differential pressure is higher than the start-
up pressure, the valve keeps flow constant at the set value.
4a. Manual Override of the M5004
If it is necessary to manually open the valve, proceed as
Remove the power supply from the motor.
Open the rubber cover on the top of the actuator and
insert the 6 mm Allen key.
