AKVH are electric expansion valves designed for refrigerating plants using R744 refrigerant. The AKVH valves are normally controlled by a controller from Danfoss’ range of ADAP-KOOL® controllers. The AKVH valves are supplied as a component programme, as follows: Separate valve. Separate coil with terminal box or cable. Spare parts such as upper part, orifice and filter. The individual capacities are 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 AKVH 10-3. The orifice assembly is replaceable. The AKVH 10 valves cover a capacity range from 0.4 kW to 11 kW in refrigeration applications and 0.8 kW to 22 kW in freezing applications.
