We offer a variety of Danfoss electronically controlled expansion valves, designed for use in ammonia refrigeration systems. The valves can be used in flooded (high/low pressure) evaporators, liquid separators and pressure fed systems. Designed to work with refrigerants: R717, R744, R134a, R22, R401A, R402A, R404A, R407A, R407B, R407C, R407F, R409A, R410A, R421A, R502 and R507 in the nominal capacity range from 4 to 3,150 kW (R717). AKVA valves are usually controlled by ADAP-KOOL controllers. Maximum operating pressure PS - 42 bar.

We are glad to present the AKVA series of Danfoss electronic expansion valve, equipped with a replaceable orifice installation and a wide range of DC and AC coils, requiring no adjustment. Provides fast response in performance range. In some applications, the AKVA valve can be used simultaneously as an expansion valve and a solenoid valve. It is characterized by durability and long service life, ensures precise temperature regulation which guarantees high food quality. Integration with the ADAP-KOOL® system ensures optimal operation.

AKVA expansion valves characteristics:

  • refrigerants: R22, R134a, R404A, R407C, R407F, R407A, R410A, R717 (ammonium), R744 (CO2)
