CAREL Electronic Expansion Valves
E2V, E3V and E4V are proportional electronic expansion valves activated by a two-pole stepper motor. Control is performed using a calibrated stem that slides through on an opening, with 14 mm travel. The stem is positioned by a stepper motor with a range of around 500 steps. The correct mechanical balance guarantees significant stability of superheat control according to the set point and a rapid response to transient situations. The proportional control also ensures no pulsation in pressure on the refrigerant lines and greater control over the return of liquid to the compressor.
ExV is available in different sizes, with cooling capacities of up to 250 kW, with different types of fittings (copper, brass, stainless steel).
