Electric expansion valves for HVAC-R
Electric expansion valves for HVAC-R are used for precise liquid injection into evaporators and accurate refrigerant flow control. In cold room systems, they help regulate refrigerant flow for stable evaporator performance, accurate control, and efficient system operation. This product range is also used outside cold rooms across air conditioning, refrigeration, food retail, chiller, and other HVAC-R applications.

AKV 10P / AKV 10PS
AKV 10P and AKV10PS are electric operated expansion valves designed for refrigeration plants.
The AKV 10P and AKV 10PS valves are normally controlled by a controller from Danfoss range of ADAP–KOOL® controllers, that ensures a precise liquid injection into evaporators.
The AKV 10P and AKV 10PS valves are supplied as a part program, as follows:
• Separate valve
• Separate coil with terminal box, DIN plug or cable
• Spare parts in the form upper part, orifice and filter
The orifice and piston assemblies are replaceable. The AKV 10P and AKV 10PS valves cover a wide capacity range.
AKV 15 / AKV 20
AKV are electrically operated expansion valves designed for refrigerating plants.
The AKV valves are normally controlled by a controller from Danfoss’ range of ADAP–KOOL® controllers.
The AKV valves are supplied as a component programme, as follows:
• Separate valve
• Separate coil with terminal box or cable
• Spare parts in the form upper part, orifice and filter
Valve capacity is indicated with a number forming part of the type designation. The number represents the size of the orifice of the valve in question. A valve with orifice 3 will for example be designated AKV 15–3. The orifice assembly is replaceable.
ETS 12.5 - ETS 400
ETS is a series of electric expansion valves for precise liquid injection in evaporators for air conditioning and refrigeration applications. The valve piston and linear positioning design is fully balanced, providing bi-flow feature as well as solenoid tight shut-off function in both flow directions.
The valve design uses bi-polar drive providing very precise flow regulation. ETS valves are compatible with electronic control solutions from Danfoss and other manufacturers.
ETS 5M
ETS 5M is a compact and lightweight stepper motor driven electric expansion valve with a high level of reliability, and it provides a precise solution for expansion and flow control in a wide range of refrigeration and air conditioning systems.
The portfolio is available with a wide capacity range and is designed for use with fluorinated refrigerants.
ETS 5M can be applied for applications i.e VRF, IT cooling, heat pump, mini chiller, bus/transport application in single/bi-flow operation.
Valve operation is by means of a unipolar/bipolar motor, and as such it is compatible with a number of electronic controllers from Danfoss or third-party vendors. With an EKE100 series superheat controllers and AKS sensor, a superheat accuracy better than ±0.5 K can be obtained.
ETS Colibri®
ETS Colibri® is an electric stepper motor valve. The valve has been designed for precise liquid injection into evaporators for air conditioning and refrigeration applications. The valve in-line design includes balanced cage and slider assembly operated by the direct driven motor technology. This ensures solenoid tight shut-off in both flow directions, thus providing smooth operation of the system. The valve incorporates a powerful bi-polar motor which precisely controls flow regulation. ETS Colibri® valves are compatible with electronic control solutions from Danfoss and other manufacturers.
Cold Rooms
Electric expansion valves for HVAC-R are used when precise refrigerant control is needed in evaporators. In cold room systems, they support accurate liquid injection and controlled evaporator performance, helping the refrigeration circuit respond more precisely to changing load conditions. The same category is also relevant outside cold rooms because these valve families are used in food retail, air conditioning, refrigeration, chillers, and other HVAC-R systems.
