Brand: Danfoss
SKU: 068G6126

Description

TEAT 20-5: a thermostatic injection valve for desuperheating ammonia

Danfoss 068G6126 is a TEAT 20-5 desuperheating valve, a thermostatic injection valve used on ammonia (R717) systems. It injects liquid into the suction gas or hot gas so that the gas temperature is held within a controlled range. This code has a 1/2 in weld-flange connection, a cast iron GGG40.3 body, a 5 m capillary and a rated capacity of 16 kW (4.6 TR) on R717.

The valve is internally equalized, has a proportional band of 20 C and works with a bulb temperature range of 35 to 65 C. The maximum working pressure is 20 bar (290 psig), the test pressure is 30 bar, and the net weight is 2.26 kg. EAC and UA approvals are listed.

Desuperheating in ammonia plants

Hot gas from screw compressors or from a defrost line can reach temperatures that hurt oil and seals. A TEAT injects a small stream of liquid ammonia into the gas, evaporating it and cooling the stream to the setting. The bulb, mounted downstream on the gas line, controls the opening so that the cooling matches the load.

The TEAT 20 family has several nominal capacities (20-2, 20-5, 20-8, 20-20) and the larger TEAT 85 sizes (85-33, 85-55, 85-85); this 20-5 has the second-smallest capacity of the 20 line. The capacity is rated at 4 K subcooling and 4 C evaporating.

Ordering and fitting

Flanges are listed as an accessory, so confirm that weld flanges are what you need. The long 5 m capillary allows the bulb to be placed far from the valve; coil excess capillary neatly and avoid kinks. Install the bulb on a straight run with good thermal contact.

Confirm that your refrigerant is ammonia, as the TEAT is for R717, and check the temperature range of the bulb against your required outlet temperature. See the data sheet for the capacity table of each size.

Other types and sizes from the same Danfoss family that appear in the Danfoss store listing include TEAT 20-2 (068G6062), TEAT 20-8 (068G6063), TEAT 20-20 (068G6064), TEAT 85-85 (068G6069), TEAT 85-33 (068G6070), TEAT 85-55 (068G6073). 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

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.
