Gas Operated Two Stage Solenoid Valves Type SPMLX
SPMLX are 2-step servo-controlled main valves with screwed on pilot solenoid valves. SPMLX valves use an external pressure source for opening (which means that no differential pressure across the SPMLX valve is required).
SPMLX 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 or fluorinated refrigerants.
