Product Features
5/2 Way Pneumatic Direction Control
The 4A220-08 double air pilot valve uses a 5-port, 2-position structure to control the extension and retraction of double-acting pneumatic cylinders and actuators.
Double Air Control with Memory Function
Unlike single air control valves, the 4A220-08 is shifted by pilot air from both sides. Double air control valves can keep their last switching position after the pilot signal is removed, making them useful for pneumatic memory circuits and stable actuator control.
1/4 Port for Practical Airflow
With a 1/4″ port size, the 4A220-08 provides suitable airflow for small and medium pneumatic cylinders, clamps, fixtures, testing equipment, and machine-side actuator control.
No Solenoid Coil Required
The 4A220-08 does not require voltage selection, electrical wiring, or PLC output. It is controlled by compressed air signals, making it suitable for pneumatic-only control systems.
Stable Sliding Spool Structure
The internal sliding spool design supports smooth shifting, good sealing performance, and reliable air direction control during repeated operation.
Durable Aluminum Alloy Body
The aluminum alloy body provides good strength, light weight, and stable performance in general industrial compressed air environments.
Easy Installation in Pneumatic Circuits
The threaded connection design supports simple installation in air control panels, pneumatic machines, fixtures, testing devices, and automated equipment.
Ideal Replacement for Airtac 4A200 Series Applications
The 4A220-08 can be selected for pneumatic systems that require a 4A200 series type 5/2 way double air pilot valve compatible with Airtac 4A200 Series installations.
Applications
The 4A220-08 double air pilot pneumatic valve is widely used in double-acting cylinder control, pneumatic actuator control, air pilot circuits, pneumatic logic systems, fixture control, clamping systems, testing equipment, packaging machinery, assembly stations, and industrial automation equipment.
It is especially suitable for applications where valve switching is controlled by compressed air signals instead of electrical signals. The double air control structure is useful for pneumatic memory circuits, actuator holding logic, air-driven sequence control, and equipment that requires stable two-position switching.

FAQ
What is the 4A220-08 pneumatic valve used for?
The 4A220-08 is mainly used to control the air direction of double-acting pneumatic cylinders and pneumatic actuators.
Is 4A220-08 a solenoid valve?
No. The 4A220-08 is more accurately described as a double air pilot pneumatic valve. It is switched by pneumatic pilot air, not by an electric solenoid coil.
Is the 4A220-08 a 5/2 way valve?
Yes. The 4A220-08 is a 5-port, 2-position pneumatic directional valve.
What is the port size of 4A220-08?
The standard main port size is 1/4″, and the exhaust port is commonly 1/8″.
What is the difference between 4A210-08 and 4A220-08?
The 4A210-08 is a single air control valve, while the 4A220-08 is a double air control valve. The 4A220-08 can keep its last switching position after the pilot signal is removed, making it suitable for pneumatic memory control.
Can 4A220-08 be used for double-acting cylinders?
Yes. Its 5/2 way structure makes it suitable for controlling the forward and backward movement of double-acting pneumatic cylinders.
How is 4A220-08 controlled?
The 4A220-08 is controlled by pneumatic pilot air pressure from both sides instead of electrical voltage.
Is this valve interchangeable with Airtac 4A200 Series?
The 4A220-08 is designed for 4A200 series type air pilot valve applications and can be selected for systems using Airtac 4A200 Series style valves.
