The control valve is operated by an electronic actuator
that responds to a standard voltage for on/off control,
a modulating VDC/4…20 mA, or 3-point control
stem. The actuator will then move the ball of the
valve to the position dictated by the control signal thus
changing the fl ow.

Mounting and Installation Instructions
Valves
(

.
Mounting
e valves can be mounted in any position, except stem below horizonta
The fl ange allows the actuator to be either parallel or perpendicular to the pipe; there
are four orientations possible
If fi eld installing a spring return actuator, disconnect power and allow actuator to spring
closed. Flip actuator over if necessary to achieve proper rotation direction. DO NOT
USE THE REVERSING SWITCH TO DO THI
Two-way Valves Mounting
For NORMALLY CLOSED operation:
The ball of the valve must be rotated so that the ball is CLOSED to fl ow. The actuator
should be mounted with the clamp fully rotated CW (R). Spring return actuators will
show the CW (R) symbol near the clamp and position indicator. Depressing the gear
release to move the clamp rotates non-spring return actuators
For NORMALLY OPEN operation:
The ball of the valve must be rotated so that the ball is OPEN to fl ow. The actuator should
be mounted with the clamp fully rotated CCW (L). Spring return actuators will show the
W (L) symbol near the clamp and position indicator. Depressing the gear release to
move the clamp rotates non-spring return actuators. There are marks on the top of the
valve stem, which indicate the port directions
Installation
1.
nspect shipping package, valve, linkage, and actuator for physical damage. I
hipping damage has occurred notify appropriate carrier. Do not install
2.
nstall valve with the proper ports as inlets and outlets. Check that inlet and outlet
f 2-way valves are correct. Flow direction arrows must be correct.
.
low out all piping and thoroughly clean before valve installation
4.
lean male pipe threads with wire brush and rag. If threads have been damaged
r exposed to weather, running a tap or die over the threads may straighten them.
lean pipes, threads, and valve threads before installation; check for any foreign
aterial that can become lodged in trim components. Strainers should be cleaned
fter initial startup
.
ipe sealing compound should be applied sparingly after cleaning and may not be
pplied to the two lead threads of a screwed pipe, which are innermost inside the
alve. Sealing compound is to be placed on male threads only. The purpose is to
ubricate the pipes when tightening.
.Valve must be installed with the stem towards the vertical, not below horizontal.
7.Start the connection by turning the valve or pipe by hand as far as possible. Be
ertain the threads mate by the “feel” of the connection.
8.
se wrenches to tighten the valve to the pipe. Do not over tighten or strip the
hreads. Two wrenches are necessary to avoid damaging the valve.
. Two-way valve Normally Open or Closed confi gurations must be verifi ed by
xamining both the mechanical drawings and the valve and actuator.
Warning!
• Valve should not be used for combustible gas applications. Gas leaks and explosions
may result. Do not install in systems, which exceed the ratings of the valve
Avoid installations where valve may be exposed to excessive moisture, corrosive
umes, vibration, high ambient temperatures, elements, or high traffi c areas with
potential for mechanical damage
Valve assembly location must be within ambient ratings of actuator. If temperature is
elow -22°F a heater is required.
• The valve assembly will require heat shielding, thermal isolation, or cooling if
combined effect of medium and ambient temperatures – conduction, convection, and
adiation – is above 122°F for prolonged time periods at the actuator.
• Following standard procedure, a strainer should be installed before the coil and valve
or in another appropriate place in the system.
Visual access must be provided. Assembly must be accessible for routine schedule
service. Contractor should provide unions for removal from line and isolation valves
Avoid excessive stresses. Mechanical support must be provided where reducers have
been used and the piping system may have less structural integrity than full pipe sizes.
• Suffi cient upstream and downstream piping runs must be provided to ensure proper
alve capacity and fl ow response. Five diameters in each direction are recommended
•Life span of valve stems and O-rings is dependent on maintaining non-damagin
conditions. Poor water treatment or fi ltration, corrosion, scale, other particulate can
esult in damage to trim components. A water treatment specialist should be consulted.
ormal thread engagement between male pipe thread and valve body should be
observed. Pipe run that is in too far will damage the valve.

Wiring Instructions

GENERAL WIRING INSTRUCTIONS
WARNING The wiring technician must be trained and experienced with
electronic circuits. Disconnect power supply before attempting any wiring
connections or changes. Make all connections in accordance with wiring
diagrams and follow all applicable local and national codes. Provide
disconnect and overload protection as required. Use copper, twisted pair
conductors only. If using electrical conduit, the attachment to the actuator
must be made with fl exible conduit.
Always read the controller manu
efore making any connections. Follow all instructions in this literature. If you
have any questions, contact the controller manufacturer and
Trans forme r(s
Typically actuators require a 24 VAC Class 2 transformer and draws a maximum of 10
VA per actuator. The actuator enclosure cannot be opened in the fi eld; there are no
parts or components to be replaced or repaired
– EMC directive: 89 /336/EE
– Software Class A: Mode of operation Type
– Low voltage directive: 73/23/ EE

ax. VA Per Actuat
CAUTION It is good practice to power electronic or digital controllers from a
separate power transformer. The power supply design in our actuators and
other end devices use half wave rectifi cation. Some controllers use full wave
rectifi cation. When these two different types of power supplies are connected
to the same power transformer and the DC commons are connected together, a
short circuit is created across one of the diodes in the full wave power supply,
damaging the controller. Only use a single power transformer to power the
controller and actuator if you know the controller power supply uses half wave
rectifi cation.
ultiple Actuators, One Transformer
Multiple actuators may be powered from one transformer provided the following rules
are followed:
1. The T
2. Polarity on the secondary transformer is strictly followed. This means that all
Multiple actuators positioned by the same control signal may be powered from
multiple transformers provided the following rules are followed
Wire Type and Wire Installation T
For most installations, 18 or 16 Ga. cable works well with Belimo actuators. Use
code-approved wire nuts, terminal strips or solderless connectors where wires
are joined. It is good practice to run control wires unspliced from the actuator to
the controller. If splices are unavoidable, make sure the splice can be reached for
TAL current draw of the actuators (VA rating) is less than or equal to the
rating of the transformer
No. 1 wires from all actuators are connected to the common le
transformer and all No. 2 wires from all actuators are connected to the hotleg.
Mixing wire No. 1 & 2 on one leg of the transformer will result in erratic operation
or failure of the actuator and /or controls.
ultiple Actuators, Multiple Transformer
. Transformers are properly sized
. All No. 1 wires from all actuators are tied together and tied to the negative leg of
the control signal. See wiring diagram
