Industrial Applications

1. Semiconductor Wafer Transfer and Holding Mechanism

Utilizing the valve's ISO 14644-14 Class 5 cleanroom suitability and compact 18 mm size, this application controls pneumatic manipulator arms that transfer fragile semiconductor wafers. The 5/3 closed configuration allows the transfer arm to be securely held in an intermediate position if a machine fault occurs, preventing dropping or damaging the wafer.

Problem Solved

Prevents wafer damage during power loss or E-stops by holding pneumatic transfer cylinders mid-stroke without introducing particulate contamination into the cleanroom environment.

2. High-Speed Diverter Gates in Automated Packaging Lines

Applied in packaging sortation conveyors, this valve uses its high 1200 l/min flow rate and fast 15 ms switching time to rapidly actuate diverter arms. The 5/3 closed position ensures that in the event of a line jam or safety interlock, the diverter cylinder stops exactly where it is, avoiding crushing the packages.

Problem Solved

Solves the need for rapid pneumatic actuation combined with mid-stroke failsafe stopping capabilities during conveyor jams or emergency stops.

3. Precision Clamping Fixture for Sub-Assembly Stations

Deployed in automated assembly cells to operate pneumatic clamping cylinders. The 100% duty cycle and soft sealing principle (HNBR/NBR) enable the valve to reliably maintain holding pressure over extended periods without leaking. The IP40 rating is ideal for indoor, dry environments where washdowns are not required.

Problem Solved

Maintains secure and drift-free holding force on mechanical components during long assembly or curing cycles without overheating the solenoid coil.
