4A230-08 Pneumatic Air Control Valve – 5/3-Way Double Air Pilot, Closed Center, G 1/4" Port AIRMIXS
The AIRMIXS 4A230-08 is a heavy-duty 5/3-way double air-piloted pneumatic directional control valve designed for precise intermediate positioning and safety stopping in pneumatic systems. Featuring a closed-center configuration, this valve traps trapped air in both cylinder ports when no pilot signal is applied, allowing double-acting pneumatic cylinders to hold their position safely during process stops.
Engineered with a durable aluminum alloy body and precision internal spool, the 4A230-08 provides exceptional flow rates, low friction, and long operational life. Its standard G 1/4" ports make it ideal for integration into packaging machinery, automated indexing tables, and complex pneumatic control circuits that require mid-stroke stopping capabilities without oil lubrication.
