General information and technical data:
110RB/200RB/240RA Solenoid Valves are used for
shut-off purpose during operation on liquid, suction and
discharge line. Valve except 540RA are normally closed
types (NC), means when coil is de-energized valve is in
closed position. 540RA is normally open type (NO).
• Max. Operating Pressure PS: 31 bar;
• Max. Test Pressure PT: 34 bar; 540RA 20: 31 bar
• Operating Temperature Range TS: –40°C to 120°C
• Max. Ambient Temperature: -40 to 50°C
• Max. Transport Temperature: -40 to 70°C
• Max. body temperature:
• Valves with Tube Connection >32mm are CE
marked, except 540RA.
• Valves are in compliance with prEN 12284

• Compatibility: CFC, HCFC, HFC, Mineral- and
Ester Lubricants
•
!
Safety instructions:
Read installation instructions
•
Failure to comply can result in device failure,
system damage or personal injury.
It is intended for use by persons having the
•
appropriate knowledge and skill. Before
attempting to install the solenoid valve make
sure pressure in system is brought to and
remains at atmospheric pressure.
• Do not release any refrigerant into the
atmosphere.
Do not use any other fluid media without prior
•
approval of Alco Controls. Use of fluid not
listed could result in:
Change of Hazard Category of the product and
consequently change of conformity assessment
requirement for product in accordance with
European Pressure Equipment
97/23/EC.
In a severely contaminated system, avoid
•
breathing acid vapours and avoid contact with
skin from contaminated refrigerant / lubricants.
Failure to do so could result in skin injury.
WARNING: Do not use a solenoid valve as a
•
safety shut-off valve or for service purpose.
The solenoid coil should be fused in accordance
•
with local codes. Electrically ground the valve
body.
• WARNING: Do not energize Coil unless it is
attached to the valve.
• 110RB/200RB/240RA are not released for use
with flammable refrigerants
hydrocarbon refrigerants and ammonia.
• Before any service disconnect power supply
from coil.
Mounting location:
• 110RB/200RB/240RA should be installed as close
as possible to the device to be shut -off/controlled
by the valve.
• Allow sufficient clearance above the valve for
removal of Coil.
• Valves may be mounted in horizontal or vertical
lines (Fig. 1). Up-side down position is not
allowed and can cause mal-function (Fig. 2).

Installation of Valve:
• Do not dent, bend, or use the enclosing tube as a
lever. A damaged enclosing tube may result in coil
burnout, inoperative valve or leakage.
• Direction of flow must match arrow on body.
• Before brazing clean tubing.
• Do not disassamble valve before brazing.
540RA 20: 28 bar • Direct flame away from valve body (Fig. 3).
• Use an inert gas such as nitrogen to pass through
the valve to prevent copper oxide formation.
• The use of appropriate brazing material is required
(soft solder is not allowed). During brazing process
120°C the cooling of the valve body is necessary to avoid
any internal damage(i.e. wet cloths). Do not
exceed max. body temperature of 120°C.
• Never use oxygen or flammable gases.
• Internal parts must be protected from foreign
material and moisture. ALCO filter-drier use in
liquid line and ALCO filter use in suction line is
recommended.
• Before energizing the valve be sure that the source
voltage and frequency matches that on the coil
label.
Installation of Coil:
thoroughly.
• Place coil over the enclosing tube. Coil may be
rotated 360° for ease of wiring.
• Press coil housing down firmly, secure (1) and
close (2) the coil retainer (Fig. 4).

such as
Testing:
• Before Testing let the parts cool down to a
temperature <40°C.
• Cycle valve several times. A distinct click should
be heard each time the solenoid is energized.
• NOTE: ALCO solenoid valves are equipped with
a continous-duty coil, which when energized for an
extended period of time becomes hot. This is
normal.
Leakage test:
• After completion of installation, a pressure test
must be carried out as follows:
- According to EN378 for systems which must
comply
directive 97/23/EC
- To maximum working pressure of system for
other applications.

Warning:
1. Failure to do so could result in loss of refrigerant
and personal injury.
2. The pressure test must be conducted by skilled
persons with due respect regarding the danger
related to pressure.
Service:
• Before any service shut down system and disconnect
from power source.
• Fully depressurize Valve. After reducing pressure to
atmospheric the valve may be opened and internal
parts removed and replaced. Clean parts before re-
installation. Install parts in reverse sequence as
removed (Fig. 6-8).
