E2V24CS000

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.

Features:

• External stator replaceable without dismantling the valve
• Gearless
• Movement on stainless steel ball bearings
• Tight when valve closed
• Control with flow in both directions
• Equipercentile variation of refrigerant flow-rate: ensures high precision control at low flow-rates
• ExV is available in different sizes, with cooling capacities of up to 250 kW, with different types of fittings (copper, brass, stainless steel).
