As today s systems require improved energy efficiency, tighter temperature control, wider range of operating conditions and incorporate new features like remote monitoring and diagnostics, the application of electronically operated valves becomes mandatory. Only they offer the Controls performance necessary to meet these control valves are actuators only. For operation in a system they need sensors, valve drivers and controllers, see next is designed for pulse width modulation.

7 It is applicable to all common HCFC and HFC refrigerants and for subcritical CO2 applications and is used mainly for refrigeration applications such as display cases. The EX2 valve is a slide type solenoid valve with an orifice for expansion. It is either completely open or completely closed. One common valve body can be combined with 6 interchangeable orifices to cover 7 capacity consist of two main internal assemblies, the valve and the stepper motor. The stepper motor is located next to the electrical plug and connected directly to the slide and cage assembly of the valve. Similar to the technology used in compressors, the motor is exposed to refrigerant and lubricant and the materials used are identical to the ones in compressor motors. The housing of the motor and valve assembly is made from stainless steel and fully hermetic, utilising exclusively brazing and welding technologies and eliminating all design offers several technical advantages such as proportional linear mass flow and a wide capacity range.

8 A common feature of all ALCO electrical control valves is the positive shut-off function, which eliminates the need for additional solenoid Selection For EX2 the published table quotes capacities at 100% duty cycle. valve open continuously. However, it is recommended to operate the valve at partial load (50-80%) to allow for system load fluctuations. For E X4/E X5/E X6/E X7/E X8 and E XM/E XL all published capacities are maximum and there are no reserve capacities. Each valve should be selected for the highest possible capacity of the system. A wide range regulation (10 .. 100%) with one slide orifice for each valve is facilate valve dimensioning for other than the standard conditions ALCO offers an Excel based Selection Tool.
