The AIRMIXS 4M420-15 is a high-flow 5/2-way double solenoid Namur valve engineered for direct flange mounting onto large pneumatic rotary actuators and process control valves. Featuring a dual-solenoid (bistable) memory function, this valve changes state when momentary power is applied to either coil and maintains its position until the opposing coil is energized, offering enhanced operational safety and position holding during system power interruptions.
Designed with a standardized Namur mounting pattern and large 1/2" porting, the 4M420-15 connects directly to actuator bodies without requiring interconnecting hoses or extra mounting brackets. Its high air throughput and internal pilot-operated spool design make it ideal for driving large-bore double-acting quarter-turn ball valves, heavy butterfly valves, and process control dampers across chemical processing, water treatment, and heavy industrial automation systems.
