Prevents total system vacuum loss when specific nozzles in a multi-head gripper do not contact a part (due to variable batch sizes or missing feeder components). Without these valves, open ports would bleed vacuum pressure, causing the remaining gripped components to drop during high-acceleration transfers.

Eliminates the need for complex active solenoid control systems to switch off specific suction zones. The valve's passive closure upon high flow (1 l/min threshold) ensures that lifting force is concentrated only on the cups sealing against boxes, while the 'Suitable for ejector pulse' rating (≤8 bar) allows for high-pressure blow-off to rapidly release heavy loads.

Maintains critical vacuum levels (-0.95 bar) for the intact wafers even if one suction point leaks due to breakage. This prevents the catastrophic drop of an entire expensive solar array. The sintered bronze filter prevents silicon dust ingestion, and the CRC 2 corrosion resistance suits the chemical environment of wafer processing.
