5. Main Product Advantages

• Enhanced multi‑stage venturi performance: Promoted vacuum level and suction flow, excellent adaptability for high‑leakage pneumatic vacuum circuits.

• Fully integrated modular options: Solenoid supply / release valve, silencer, mechanical / digital vacuum gauge and pressure switch are available for one‑piece configuration, minimizing extra auxiliary parts.

• Low‑noise construction: Built‑in silencer, noise level ≤70 dB, friendly for ordinary factory workshop environment.

• Maintenance‑free stable operation: Zero moving mechanical components, long service life for 24‑hours continuous production.

• Compatible mounting footprint: Interchangeable installation dimension with ZL112, supports direct field upgrade replacement.

6. Quick Selection Guidance

• Small‑medium workpiece & single suction‑cup application: Choose ZL112 for better cost‑performance.

• Large suction cup, porous material, sheet glass or high‑leakage vacuum loop: Adopt ZL212 for sufficient vacuum and flow capacity.

• Automatic cycle control: Select K1 dual‑valve version (supply + release valve), match with vacuum pressure switch for closed‑loop signal feedback.

• On‑site visual monitoring & commissioning: Pick D digital pressure‑switch variant for direct digital vacuum‑value reading.

7. Typical Application Scenarios

• Robotic handling for glass, sheet metal, wood board and large‑size plate components

• Porous workpiece adsorption: carton, foam, textile and permeable material picking

• High‑leakage vacuum circuit for large‑area multi‑suction‑cup fixture

• Automation assembly line, injection‑molding robot demolding and material transfer

• Logistics equipment large‑size goods vacuum grabbing station
