ISV-M6 Festo Vacuum security valve

Model Identifier ISV-M6
Official Part Number 545997
GTIN Standard 4052568092009

Technical Overview

The Festo ISV-M6 is a compact vacuum security valve designed to maintain system vacuum integrity when suction cups fail to make contact with a workpiece. This screw-in valve features an M6 connection and operates within a vacuum range of -0.95 to 0 bar. Built with a wrought aluminium alloy housing and a sintered bronze filter, it provides reliable performance for automation systems, requiring a suction volumetric flow of 2 l/min at -0.5 bar to function effectively.

Key Features

  • Suitable for ejector pulses up to 0.8 MPa (8 bar)
  • Optional mounting position for flexible installation
  • CRC 2 - Moderate corrosion stress resistance
  • LABS (PWIS) conformity to VDMA24364-B1/B2-L
  • High-alloy steel spring and wrought aluminium alloy housing
  • Integrated sintered bronze filter for component protection

Compact M6 screw-in vacuum security solution with integrated sintered bronze filtration and moderate corrosion resistance for reliable vacuum system protection.

Industrial Applications

1. Flexible End-of-Line Palletizing Gripper

Integration of the ISV-M6 into a large-area vacuum gripping system for palletizing varying box sizes and layer patterns in logistics centers. The valve is installed directly at the M6 port of each individual suction cup within the gripper matrix.

Problem Solved

In standard palletizing, changing box sizes or incomplete layers leave some suction cups exposed to open air, causing immediate system vacuum loss and dropped loads. The ISV-M6 automatically closes off these unsealed cups based on airflow velocity, allowing a single gripper tool to handle mixed SKUs and random patterns without complex valving or tool changes.

2. High-Speed Electronics Component Tray Unloader

Use in robotic pick-and-place end-effectors for handling batches of PCBs or electronic components (e.g., battery cells) from trays. The lightweight (14g) valve mounts inline with miniature suction cups to minimize robot arm inertia.

Problem Solved

When picking components from partially filled trays or if a component is missing, open suction cups would normally deplete the vacuum level for the successfully gripped parts. The ISV-M6 isolates the open lines, ensuring the remaining components are held securely at -0.95 bar, reducing scrap rates and eliminating the need for camera-based individual cup control.

3. Stamped Sheet Metal Transfer System

Application in press shop automation for transferring sheet metal parts with irregular cutouts or holes. The ISV-M6 is screwed directly into the suction cup holders on the transfer spider.

Problem Solved

Suction cups often land on holes, die-cuts, or edges of stamped metal parts, creating massive leaks that compromise the grip on the metal panel. The valve's sintered bronze filter protects against oily environments while the float mechanism instantly seals leak paths. The 8 bar ejector pulse compatibility ensures rapid, forceful part release during high-speed press cycles.
