Danfoss 027H1029 ICM 20-B Motor Operated Valve, 25 mm Butt Weld

Description

ICM 20-B: a Kv 2.4 motor-operated valve body with 25 mm connections

The 027H1029 is an ICM 20-B motor-operated valve body, one flow step above the ICM 20-A. The steel body has 25 mm (1 in) butt-weld connections to EN 10220 and a Kv value of 2.4 m3/h. The maximum working pressure is 65 bar (943 psig), higher than the 52 bar of the ICM 20-A, and the temperature range is -60 to 120 C.

Like all ICM bodies it is paired with an ICAD actuator through a magnetic coupling, opens or closes in 3 s and has manual operation through the actuator setting or the multifunction tool. The surface is zinc coated (TLP), and the valve is listed for oil-free refrigerants R1234ze(E) and R134a.

Where ICM valves are used

The B size covers evaporator feed and bypass duty on medium-capacity ammonia circuits, and hot-gas defrost branches. Its Kv value is four times that of the A size, so choose it when the A size would throttle the flow. UL, EAC and UA approvals are listed.

Because it is the same platform as the ICS pilot-operated valve and the ICF valve station, spares and accessories can be shared between ICM, ICS and ICLX bodies, as the product page notes.

Actuator, commissioning and checks before ordering

The ICAD 600B actuator is the one listed for ICM 20, 25 and 32; the ICAD 1200B is for ICM 40 and larger. Order the actuator separately and check its communication type (Bluetooth, display, RS485 or Ethernet) for your control system.

Pressure test limits and weld procedures are in the installation guide for ICM 20 – 65. Confirm Kv, refrigerant and pressure class before ordering; do not use the valve as a shut-off device unless the controller is set to full close.

Other types and sizes from the same Danfoss family that appear in the Danfoss store listing include ICM 20-A HT (027H1176), ICM 20-B HT (027H1177), ICM 20-C HT (027H1178), ICM 20-B66 HT (027H1179), ICM 20-A (027H1180), ICM 20-C (027H1182), ICM 20-A33 (027H1186), ICM 20-B66 (027H1194). These are listed for orientation only; each has its own datasheet values, so check size, connection and version before ordering.

About brand

Danfoss is the Danish engineering group that makes refrigeration and air-conditioning controls, heating components, variable speed drives and mobile hydraulics. Mads Clausen founded it on 1 September 1933 at his parents' farm in Nordborg on the island of Als, after making his first refrigeration expansion valve in 1932. Nordborg is still the group's headquarters, and Danfoss remains controlled by the Clausen family through the Bitten & Mads Clausen Foundation.

Danfoss company profile

Founded 1 September 1933, Nordborg, Denmark, by Mads Clausen (1905–1966)
First product Thermostatic expansion valve for refrigeration
Headquarters Nordborg, Denmark
Ownership Private; majority controlled by the Bitten & Mads Clausen Foundation and the Clausen family
Size About 42,000 employees (2023)
Business segments Danfoss Climate Solutions (refrigeration, air conditioning and heating), Danfoss Drives (VLT and VACON frequency converters, soft starters), Danfoss Power Solutions (mobile and industrial hydraulics)

Milestones

  • 1932–1933: First expansion valve; the company is founded in Nordborg.
  • 1939: 26 employees. By the 10th anniversary in 1943 the company has 179.
  • 1950s: Rapid growth turns Nordborg into a Danfoss town with housing and schools for its workforce.
  • 1968: Danfoss launches its VLT frequency converter, one of the first mass-produced AC drives.
  • 2014: Acquisition of the Finnish drives maker Vacon, now the VACON brand.
  • 2021: Acquisition of Eaton's hydraulics business.

Choosing Danfoss products

For solenoid valves, check the operating principle. A direct-operated valve such as EV210B opens even at 0 bar differential pressure. A servo-operated valve such as EV220B needs a minimum differential (typically about 0.3 bar) to open, while an assisted-lift valve such as EV250B works from 0 bar. Coils are ordered separately, so the voltage on the coil (for example 230 V AC or 24 V DC) must match the control circuit. For drives, the VLT family is split by application: FC 51 Micro Drive for small machines, FC 102 HVAC Drive for fans and pumps in buildings, FC 202 AQUA Drive for water, and FC 302 AutomationDrive for demanding industrial duty.

Where Danfoss products are used

In Oman and the GCC, Danfoss drives run pumps, fans and compressors in district cooling plants, water and wastewater stations, desalination and building HVAC. Danfoss pressure switches, transmitters and solenoid valves are built into chillers, refrigeration plants, boilers and hydraulic systems, and AB-QM valves balance chilled-water circuits in large buildings.

Ordering Danfoss products: what we need

Send the Danfoss code number from the label (for example 032U7115 or 131B0149) or the full drive type code (FC-302P3K0T5...). For drives, add the motor power, supply voltage and any fieldbus option. For valves, add the size, connection, medium and coil voltage. For pressure switches and transmitters, add the range, output and pressure connection.
