ICLX
ICLX 2-step solenoid valves belong to the ICV family. ICLX are used in suction lines for the opening against high differential pressure, e.g. after hot gas defrost in large industrial refrigeration systems with ammonia, fluorinated refrigerants or CO2. The small sizes are designed for MWP of 65 bar, while large sizes have MWP of 52 bar. The ICLX valve is factory configured to open in 2 steps. By following a simple procedure, the valve can be configured to open in 1 step only. In 2-step configuration, step 1 opens to approx. 10% of the capacity after the pilot solenoid valves are energized. Step 2 opens automatically when the pressure differential across the valve has decreased to approx. 1.25 bar / 18 psig. The ICLX valve comprises five main components: Valve body, top cover, function module and 2 pilot solenoid valves. On ICLX 32 – 150 the top cover and function module are factory assembled.
Features and benefits
- Designed for industrial refrigeration applications for a maximum working pressure of:
- Can be used in chemical and Petro-Chemical applications
- Direct welded connections and connection types include butt weld, socket weld and solder connections
- Connection types include butt weld, socket weld and solder connections
- Lightweight, compact steel body for low temperatures
- The ICLX main valve top cover can be oriented in any direction without the function of pilot valves being affected
- Especially suitable for systems where low-pressure drop is required
- Stabilizes working conditions and eliminates pressure pulsations during opening after defrosting
- Provides safety against pressure "shocks" as the valve can only open fully when Δp < 1.25 bar / 18 psig
- Cavitation resistant valve seat and PTFE seat provides excellent valve tightness
A superior solution for safety and convenience
The new ICLX valves are part of the Danfoss ICV Flexline™ series. The ICLX valves are 2-step servo-operated main valves with pilot solenoid valves.
ICLX valves can be used in suction lines for opening against high differential pressure, for instance after hot gas defrosting in large industrial refrigeration systems with all normal, non-flammable refrigerants, including ammonia and CO₂.
The ICLX valves feature all the characteristics of ICV Flexline™ valves and offer safe, flexible and convenient installation, operation and service. For instance, the standard ICV Flexline™ housing makes the ICLX valves a true plug and play solution with easy and time-saving switch between the functions.
- Full, hermetic external tightness preventing leakage
- Normal closed type minimizes the system risk
- Direct weld eliminates pipe flanges to increase system safety and simplify installation
- Outstanding flow characteristic, ideal for systems where low pressure drop is required
- Simple installation
- No hot gas leakage to the suction line due to teflon valve plates and gas tight piston rings
