4A330-10 Pneumatic Air Control Valve – 5/3-Way Double Air Pilot, Closed Center, G 3/8" Port AIRMIXS
The AIRMIXS 4A330-10 is a high-flow 5/3-way double air-piloted pneumatic directional control valve designed for precise intermediate positioning and safety holding in automated pneumatic systems. Featuring a closed-center configuration, this valve traps compressed air in both cylinder lines when no pilot signal is applied, enabling double-acting air cylinders to hold their position safely during emergency stops or mid-stroke pauses.
Engineered with a durable aluminum alloy casing and a precision internal spool assembly, the 4A330-10 offers low actuation friction, rapid response, and extended service life. Its G 3/8" porting delivers high flow rates, making it ideal for medium-to-large air cylinders in packaging equipment, material handling setups, and industrial automation machinery without requiring oil lubrication.
