About the AirTAC 4A300
The AirTAC 4A300 is a spool-type air-piloted (pneumatically operated) valve: an air signal on the pilot port switches it, so it needs no coil or electrical connection. 5/2 versions come with a single pilot and spring return (10) or a double pilot (20), which keeps its last position; 5/3 versions have a closed (30C), exhaust (30E) or pressure (30P) center. Ports: In = Out = Exhaust = 1/4"; In = Out = 3/8", Exhaust = 1/4". Effective area: 4A310-10 / 4A320-10: 28.0 mm² (Cv 1.65); 4A330C-10: 21.3 mm² (Cv 1.25).
Operating pressure 0.15 - 0.8 MPa (21 - 114 psi), proof pressure 1.2 MPa (175 psi), temperature -20 to +70 °C, aluminium alloy body. No lubrication is needed; once lubricated, keep using the same oil (ISO VG32 or equivalent). Maximum frequency: 4A310 / 4A320: 4 cycles/s; 4A330: 3 cycles/s. Several valves of the same series mount side by side on a 300M manifold.

Where the 4A300 Is Used
Air-logic control
Switches cylinders from an air signal where no electricity is wanted.
Hazardous or wet areas
No coil, so nothing electrical at the valve.
Valve banks
Mounts on 300M manifolds.
Choosing the Right 4A300 Configuration
Start with the function: 5/2 single air pilot (10); 5/2 double air pilot (20); 5/3 closed center (30C); 5/3 exhaust center (30E); 5/3 pressure center (30P).
Then the port: 1/4" (08), 3/8" (10).
The thread is PT unless the code ends in G (G thread) or T (NPT).
AirTAC 4A300 FAQ
