03152704 (full part numbers often include a suffix, such as 03152704-xx or Sxx) is a proportional pressure control valve used in the pneumatic system of ASM SIPLACE X-series pick-and-place machines; its official designation is "Proportional Controller Sentronic-LP."
Core Function and Purpose
Installed at a specific position (Location 4) within the machine's pneumatic system, this valve precisely regulates compressed air to the operating pressure required by the placement head—typically 4.8 ± 0.1 bar—ensuring a stable air supply for vacuum generation and component pickup. As a closed-loop pressure regulation component, it features an integrated pressure sensor that monitors the output pressure; if the pressure drops below 4.5 bar, the unit triggers an alarm signal via the CAN bus.
