4A310-08/10, 4A320-08/10 AIRTAC 4A300 Series 5/2 way Air Valve 1/4" 3/8"
The AIRTAC 4A300 Series is a line of 5/3-way pneumatically operated directional control valves, meaning they have five ports and three distinct positions. These valves are externally air-piloted and designed to control the direction of airflow in pneumatic systems, making them ideal for operating double-acting cylinders and other actuators. Key specifications include an operating pressure range of 0.15 to 0.8 MPa, a proof pressure of 1.2-1.5 MPa, and a wide operating temperature range from -20°C to 70°C. A defining feature of the 5/3-way models is the availability of three center position functions: closed center (model suffix C), exhaust center (suffix E), and pressure center (suffix P), providing flexibility for different control needs such as holding, floating, or pressurizing an actuator in its mid-position.

[Note1] PT thread, G thread and NPT thread are available.
[Note2] Once lubricated air is used, continue with same medium to optimise valve life span. Lubricants like ISO VG32 or equivalent are recommended.
[Note3] The maximum actuation frequency is in the no-load state.
[Note4] Equivalent orifice S and Cv are all calculated from the flow rate data.
