Frequently asked questions

What do 5/2 and 5/3 closed centers mean, in exhaust or pressure?

In pneumatic valves, the first number indicates the number of ports (inlets) of the valve, while the second indicates the number of positions.

  • 5/2 Valve: has 5 ports and 2 positions. It is commonly used to control a double-acting pneumatic cylinder, alternating the supply to the two chambers.
  • 5/3 Valve: has 5 ports and 3 positions. In addition to the two control positions, it has a central position that can have different configurations.

The main configurations of the central position are:

  • Closed centers: the ports are blocked. The cylinder tends to maintain its position, although any air leaks or external loads may cause it to shift.
  • Exhaust centers: the cylinder chambers are connected to exhaust, allowing the piston to move more freely.
  • Pressure centers: both chambers are supplied; the behavior of the cylinder depends on the piston surfaces and the applied forces.

ATTI offers various configurations of AirTac pneumatic valves.
