4A400 Series Pneumatic Directional Air Valve 5/2 5/3 Way Control Valve 4A410 4A420 4A430C 4A430E 4A430P

Specification 4A400:

Product Overview

The 4A400 Series pneumatic directional control valve is designed to control compressed air flow direction in industrial pneumatic systems. It precisely switches air supply and exhaust flow to operate pneumatic cylinders and actuators. With support for 5/2 way and 5/3 way configurations, the 4A400 series is ideal for applications requiring high airflow capacity and stable performance in industrial automation systems.

Key Features

1. Sliding spool structure ensures fast response and reliable sealing performance
2. Body made from high-strength aluminum alloy for durability and lightweight design
3. Precision-machined internal air channels to increase airflow capacity and reduce pressure loss
4. Multiple center functions available for 5/3 valves (closed center, exhaust center, pressure center)
5. Double air control valves include memory function for stable operation
6. Can be mounted on a manifold to form valve groups, saving installation space
7. No lubrication required, reducing maintenance costs
