Key product series
PEV series pulse expansion valves are designed for precise refrigerant flow control in refrigeration systems. They operate at a maximum working pressure of 90 bar (approximately 1,305 psi), support R744 (CO2) as well as various HFC and HFO refrigerants, and use pulse-width control to regulate flow.
SEK series electronic expansion valve kits combine SEC controllers with sensors and electrical accessories for superheat control.
DPF-TS/S series electronic expansion valves are intended for air conditioning, refrigeration, and heat pump applications. They support bidirectional refrigerant flow and offer cooling capacities from 2 to 121 kW (approximately 6,824 to 412,900 BTU/h) with R410A. The range is compatible with several refrigerants, including R32, R290, R1234yf, and R1234ze(E).
Application diagrams
Beyond individual product specifications, the catalogue includes application diagrams for commercial refrigeration installations, VRF air conditioning systems, and heat pumps. These illustrate the integration of expansion valves, controllers, pressure sensors, and other components into refrigeration and heating circuits.
