Solenoid Valve

Solenoid Valve EVRA

EVRA is a direct or servo operated solenoid 
valve for liquid, suction and hot gas lines with 
ammonia or fluorinated refrigerants. EVRA valves are supplied complete or as 
separate components, i.e. valve body, coil and 
flanges can be ordered separately. EVRAT is an assisted lift, servo operated 
solenoid valve for liquid, suction and hot gas 
lines with ammonia and fluorinated 
refrigerants. EVRAT is specially designed to open – and stay 
open – at a pressure drop of 0 bar. The EVRAT 
solenoid valve is thus suitable for use in all 
plant where the required opening differential 
pressure is 0 bar. EVRAT is available as components, i.e. valve
body, flanges and coil must be ordered
separately. EVRAT 10, 15 and 20 all have spindle for manual operation.

Features and benefits

ICS Pilot Operated Servo Valve

ICS pilot-operated servo valves belong to the 
ICV (Industrial Control Valve) family. The valve comprises three main components : valve body, function module and top cover. ICS pilot-operated servo valves are pilot 
operated valves for regulating pressure, 
temperature and ON/OFF function in 
refrigeration systems. ICS valves are designed 
for low and high-pressure refrigerants. The small sizes are designed for MWP of 65 bar, while large sizes have MWP of 52 bar. ICS valves can be used on the high and 
low pressure sides, in wet and dry suction line s
and in liquid lines without phase change (i.e. 
where no expansion takes place in the valve). The function of ICS valves is dependent on the
pilot pressure applied from either a pilot valve
or external pilot pressure source. ICS 1 pilot has one pilot pressure connection and ICS 3 pilot has three pilot pressure connections.

Features and benefits

  • Applicable to HCFC, HFC, R717 (Ammonia) and R744 (CO2 ).
  • Direct coupled connections
  • Connection types include butt weld, socket weld, solder and threaded connections
  • Low temperature steel body.
  • Low weight and compact design.
  • V-port regulating cone ensures optimum regulating accuracy particularly at part load.
  • Function module has a QPQ surface treated insert and a steel piston ring ensuring precise control accuracy
  • ICV 4 in., 5 in. and 6 in. ANSI with NPT threaded pressure outlet in the outlet of the valve.
  • Replaceable Teflon valve seat for ICS 25-80.
  • Maintenance spare part kit available for ICS 100-150
  • Manual opening.
  • The ICS valve is a multifunction valve where several pilot valves can be mounted into the pilot ports
  • The standard range of pilot valves can be used on all sizes of ICS valves. Pilot valves can be either screwed directly into the ICS valve, thus eliminating the need for solder/weld connections or external pilot lines.
  • Pressure gauge connection port to measure valve inlet pressure
  • The top cover can be rotated into any possible position without affecting the operation of the valve.

Pilot Valves

Pilot valves are intended for mechanical control
of a main valve and are ready for direct
installation in the top cover of the main valve. Small capacities can be controlled by the pilot
valve directly without a main valve when
installed in the matching CVH housing.

Features and benefits

  • Applicable to HCFC, non flammable HFC, R717 (Ammonia) and R744 (CO2 ). The use of Pilots with flammable hydrocarbons is not recommended.
  • Extremely accurate pressure and temperature control.
  • The pilot valves can be screwed directly into the main valve, thus avoiding the necessity of welding, soldering and separate pilot lines.
  • The pilot valves can be mounted directly in the ICS, PM or ICF valve or it can be connected via an external pilot line and a CVH housing.
  • All pilot valves can be used on all sizes of main valves.
  • Several pilot valves can be connected in series or in parallel to provide many functions in the same ICS or ICF valve.
  • All pilot valves are delivered with gaskets

Motor Operated Valve ICM

The motor operated ICM valve comprises four
main components: Valve body, top cover,
function module and Actuator. On ICM 20 – 65
the top cover and function module will be
combined. ICM are motor operated valves
driven by actuator type ICAD. The sizes DN25 to DN65 are designed for MWP
of 65 bar, while all other sizes have MWP of 52
bar. ICM valves are designed to regulate an
expansion process in liquid lines with or
without phase change or control pressure or
temperature in dry and wet suction lines and
hot gas lines. ICM valves are designed so that
the opening and closing forces are balanced,
therefore, only two sizes of ICAD actuators are
needed for the complete range of ICM from DN
20 to DN 150. The ICM motor operated valve
and ICAD actuator assembly offers a very
compact unit with small dimensions

Features and benefits

  • Applicable to HCFC, HFC, R717 (Ammonia) and R744 (CO2 )
  • Direct coupled connections
  • Connection types include butt weld, socket weld, solder and threaded connections
  • Low temperature steel body
  • Low weight and compact design
  • V-port regulating cone ensures optimum regulating accuracy particularly at part load
  • Cavitation resistant valve seat on A cones to be used for valves operating as expansion valves. For control valves both A and B cones are allowed
  • Each valve body is available with several different connection types and size
  • Valve overhaul is performed by replacing the function module (ICM 20 – 65)
  • Possible to convert ICM motor operated valve to ICS pilot operated servo valve
  • Spare parts available for ICM 100 – 150
  • Manual opening possible via ICAD or Multifunction tool
  • PTFE seat provides excellent valve tightness

Actuator ICAD

Actuator types ICAD 600B and 1200B are 
dedicated for use with ICM motor operated 
valves. There are only two sizes of ICAD 
actuators that cover the range of valves from 
ICM 20 to ICM 150. The ICAD is controlled via a modulating 
analogue signal (e.g. 4 – 20 mA / 2 – 10 V), a 
digital ON / OFF signal or via data 
communication (Modbus RTU (RS485) or TCP/IP
(Ethernet)). ICAD B incorporates an advanced 
MMI (Man Machine Interface) display with 
descriptive text and Icons, which gives the user 
a very intuitive, advanced and flexible set up 
procedure that can meet different applications. 
In addition to the display interface, ICAD B also 
in corporates Bluetooth communication to a 
mobile app and data communication.
