应用场景
适用于制造业中的自动化生产线，如包装机械、装配设备及物流分拣系统。在食品饮料行业可用于灌装机阀门控制，亦能配合实验室精密仪器实现气路切换。其稳定性能在频繁启停的工况下仍保持可靠，兼容G1/4（进气/出气）与G1/8（排气）接口，便于集成到现有气动回路中。1523
Product Overview
The 4A21008 5/2-way single solenoid pneumatic valve is a high-performance pneumatic control component featuring a spool-type structure for precise directional flow switching. It operates via external air pressure signals to actuate the spool, enabling efficient control of double-acting cylinders or actuators in automated systems. With its compact design and versatile mounting options, it suits diverse industrial applications. 820
Key Features
The valve’s precision-machined inner bore reduces friction, allowing low actuation pressure and long service life without lubrication. The aluminum alloy body offers durability while maintaining lightweight performance. Its 5-port 2-position configuration (1 inlet, 2 outlets, 2 exhausts) ensures bidirectional flow control with a effective flow area of 16mm². Compatible with filtered compressed air (40μm filtration), it operates within -5°C to 60°C and 0.15~0.8MPa pressure range. 327
Applications
Ideal for automated manufacturing systems including packaging machines, assembly lines, and sorting equipment. In food processing, it facilitates valve control in filling devices, while its reliability supports precise pneumatic circuits in laboratory instruments. Standard G1/4 (inlet/outlet) and G1/8 (exhaust) ports ensure easy integration into existing setups. 1523
