System description

AirBox with 2 x 3/2-way Slide valves This type of AirBox has two independent 3/2-way Valves, enabling triggering of single-acting actuators, e.g. cylinders with return Springs. The M12 Sockets with two or four inputs (Y-circuit) enable feedback via Inductive sensors or Cylinder sensors. All AirBoxes have a common exhaust (tube connection). So, the user can decide whether the exhaust air is discharged via a tube or via a silencer. The protection rating is IP 65 or IP 67. The AirBox requires a minimum pressure of 2 bar in order to operate the main valve via the pilot valve. The maximum pressure is 8 bar, the pressure peak resistance 12 bar.

AirBox with 5/2-way slide valve – monostable The AirBox has a fully integrated 5/2-way valve in the form of a slide valve. It requires a minimum pressure of 3 bar in order to operate the main valve (5/2-way slide valve) via the pilot valve. The maximum pressure is 8 bar, the pressure peak resistance 12 bar. The AirBox in monostable design is necessary if the cylinder (piston rod) is to retract into a safe/defined position when the e-stop function is activated.
