Description
The 4L Series Push-Pull Valve is a manually operated 5/2-way pneumatic directional control valve designed for reliable control of compressed air systems. Featuring a simple push-pull actuation mechanism, the valve allows operators to quickly switch airflow direction with precise manual control.
Built with a spool-type valve structure, the 4L Series delivers excellent sealing performance, low operating friction, and dependable service life. The specially finished internal surfaces reduce wear and enable low-pressure startup, making the valve suitable for a wide range of industrial pneumatic applications.
Its compact aluminum alloy body offers lightweight durability while supporting flexible mounting positions for easy machine integration. Available in multiple port sizes from 1/8″ to 3/8″, the 4L Series is ideal for controlling double-acting cylinders, pneumatic actuators, automation systems, and machinery requiring dependable manual directional control.
