The EX4 / EX5 / EX6 / EX7 / EX8 stepped motor controlled electronic regulation valves from ALCO CONTROLS precisely control the flow of refrigerant in refrigeration and air conditioning application, industrial process cooling as well as in heat pumps and cooling equipment for IT facilities. They can be used as expansion valves, reinjection valves, hot gas bypass regulators, evaporating pressure or starting pressure regulators and as condensing pressure regulators or fluid level regulators.
Features
- Multifunction valves, for use as expansion valve, hot gas bypass regulator, evaporator or condenser pressure regulator, etc.
- Fully hermetic design (no screw connections between the valve body and motor part)
- For use with all common refrigerants (HFC, CFC) and subcritical CO2 applications
- Stepped ...
- Multifunction valves, for use as expansion valve, hot gas bypass regulator, evaporator or condenser pressure regulator, etc.
- Fully hermetic design (no screw connections between the valve body and motor part)
- For use with all common refrigerants (HFC, CFC) and subcritical CO2 applications
- Stepped motor operation
- Very fast opening and closing times
- Good precision and excellent repeat accuracy
- Biflow versions for heat pumps
- Closing function means an additional solenoid valve is not required
- Flow rate linearly proportional to step rate
- Large regulating range (10 ... 100%)
- Proportional regulation of mass flow avoids refrigerant hammering in the refrigeration circuit
- Motor and valve directly coupled for excellent reliability (no gears)
- Valve slider and seat made from ceramic for minimal throughput losses and low wear
- Patented in Europe (no. 0743476), USA (no. 5735501)
- Corrosion-resistant stainless steel housing
- PS: 45 bar
- TS: Uniflow: -50 to +100 °C, Biflow: -40 to +80 °C
