This product line meets cooling capacity requirements up to 2,000 kW in air conditioning and refrigeration applications.

In this month’s troubleshooting situation the equipment that needs servicing is a split system and the refrigerant flow control is handled via an electronic expansion valve (EEV) shown in Figure 1.

These lead-free cold expansion pex ball valves are designated full port valves and feature waste drain and drop ear elbows and blowout-proof stems. 

The Modular Silicon Expansion Valve (MSEV) from DunAn Microstaq (DMQ) is a fast-responding electronic expansion valve that can be used in a variety of refrigeration applications, including display cases, freezers, and walk-in and reach-in coolers.

The EX3 is a stepper-motor-driven electronic expansion valve (EXV) that provides precise mass flow control and high energy efficiency for supermarket showcases and cold rooms with multiple parallel evaporators.
