Industrial Applications

1. Automotive Body-in-White Welding Fixture Clamping

In the automated assembly of vehicle chassis (Body-in-White), this valve is integrated into the VTSA valve terminal islands to control the pneumatic toggle clamps that secure sheet metal panels during robotic welding.

Problem Solved

Ensures failsafe operation where the clamps default to a safe state (locked or open) upon power loss due to the monostable spring return. The ISO 15407-1 standardization allows for rapid 'hot-swap' replacement during line stoppages, minimizing downtime in high-volume automotive production.

2. High-Speed Conveyor Reject Pusher System

Used in packaging lines to actuate a double-acting pneumatic cylinder that rapidly ejects defective products from a moving conveyor belt.

Problem Solved

The valve's fast switching time (25ms ON) and 100% duty cycle capability allow it to keep up with high-throughput sorting lines (e.g., >100 parts/minute). The pneumatic spring reset ensures the pusher retracts immediately if the electrical signal is lost, preventing jams.

3. Vacuum Switching for Robotic Palletizing Grippers

Controls the vacuum supply to a suction cup array on a robotic arm, utilizing the valve's ability to operate with negative pressure (-0.9 bar) when supplied with external pilot air.

Problem Solved

Allows a single valve to switch between vacuum (grip) and atmospheric pressure (release) for handling porous corrugated boxes. The external pilot supply keeps the valve switching reliably even when the main line is under vacuum, while the high flow (1400 l/min) compensates for vacuum leakage on cardboard surfaces.
