After gas release, block outside air! Suitable for fermentation feed production using beer lees, fruit lees, etc. during fermentation.
We handle the adhesive valve "Gas Release Valve for Large Bags." By attaching it to large bags such as inner liners of flexible containers, it allows for the release of gas generated from fermentation, prevents increases in internal pressure due to rising external temperatures or filling of hot materials, and helps prevent bag rupture and load collapse. Additionally, it blocks outside air after gas release. Please create a hole of approximately 15mm at the top of the target bag and attach the adhesive valve by covering the hole with the double-sided tape provided. 【Specifications】 ■ Material - Main body: Polyethylene/Nylon - Tape section: Rubber, Paper ■ External dimensions: 100×120mm ■ Opening pressure: 10KPa or less (design value) *For more details, please refer to the PDF document or feel free to contact us.
