AKO Pinch Valves: Filling and Dosing Technology
Filling processes range from single portions measured to the gram up to big bags weighing several hundred kilograms, and demand maximum repeatability at short cycle times. Many media are dusty, sticky or abrasive and tend to form lumps. AKO pinch valves shut off the material flow precisely and drip-free, are insensitive to build-up and are also available in hygienic versions for sensitive food and pharmaceutical products.
Typical applications
- Filling and emptying of storage silos
- Flow control in pipelines along the entire process chain
- Filling into sacks, drums, barrels and big bags
- Portion-accurate dosing of powders, granulates or liquids
- Sterile filling in food and pharmaceutical production
Recommended AKO series
- AKO VF (flange, DN40-300) – robust, high-volume big bag and sack filling with high throughput
- AKO VMP (female thread, DN10-50, POM) – compact, for frequent switching cycles with finely dosed portions
- AKO VMCE (hygienic, EHEDG, DN10-100) – hygienic and CIP/SIP-capable for food and pharmaceutical filling
- AKO VMC (multi-connection, DN25-150) – universally applicable for different connection requirements
Case study
A manufacturer of big bag filling systems struggled with slide gates that quickly wore out and seized due to abrasive bulk solids. Since then, the company has equipped its systems as standard with AKO pinch valves, which combine dosing and shut-off in one simple, low-maintenance component – successfully in use with cement and granulates for more than 25 years, with noticeably lower maintenance effort.
