AMLX are two steps servo-operated normally close valves with screwed-on pilot solenoid valves.Valves use an extemal pressure
source for opening (which means that no differential pressure across the AMLX valve is required).
AMLX are used in suctionlines for the opening against high differential pressure, e.g. after hot gas defrost in large industrial
refrigeration systems with ammonia or fluorinate refrigerants
AMLX opens in two steps:
Step one opens to approx.10% of the capacity, when the pilot solenoid valves are activated.
Step two opens automatically after the pressure differential across the valve reaches approximately 1-1.5 bar.
