The AIRMIXS 4A220-08 is a high-performance 5/2-way double air-piloted directional control valve engineered for demanding industrial pneumatic systems. Utilizing dual external pneumatic pilot signals to switch positions, this valve maintains its actuation state until a reverse signal is applied, providing reliable memory-function control for double-acting air cylinders and automated pneumatic circuits.
Built with a durable aluminum alloy body and a precision internal spool construction, the 4A220-08 delivers quick response times, minimal friction, and excellent flow performance. Its standard G 1/4" ports allow easy integration into packaging lines, material handling equipment, and general automation assemblies without requiring oil lubrication.
