4A430-15 Pneumatic Air Control Valve – 5/3-Way Double Air Pilot, Closed Center, G 1/2" Port AIRMIXS
The AIRMIXS 4A430-15 is a high-flow 5/3-way double air-piloted pneumatic control valve designed for intermediate positioning and holding control in heavy-duty pneumatic systems. Featuring a closed-center configuration, this valve traps compressed air in both cylinder ports when no external pilot signal is present, enabling double-acting pneumatic cylinders to maintain their exact position during operational stops or power interruptions.
Constructed with a heavy-duty aluminum alloy body and precision-machined internal spool structure, the 4A430-15 ensures rapid response, low friction, and long-term durability. Its large G 1/2" ports handle high volumetric air movement, making it an ideal choice for large-bore air cylinders, heavy material handling machinery, and automated industrial assembly lines operating without oil lubrication.
