4A series is the industry benchmark for air-piloted directional control. Designed for high-frequency switching and long-term durability, these valves operate using external air pilot signals rather than electrical solenoids. This makes them the perfect choice for explosion-proof environments, high-temperature areas, or systems where purely pneumatic logic is required.


From the compact 100 series for space-saving applications to the high-flow 400 series for heavy-duty actuators, the 4A family offers a versatile range of configurations, including 5/2 way single/double control and 5/3 way centering functions.
