Forage Gas Relief Valve
One‑way venting for better fermentation, lower spoilage, and fewer popped bags.
Developed by Feed Stuff Bagging, the Forage Gas Relief Valve (Auto Bag Valve) is a simple, field‑proven solution that lets excess fermentation gases escape
without letting oxygen back in. By maintaining a slight internal pressure while blocking air from re‑entering, it supports more stable fermentation, a lower
final pH, and improved feed value.
Why Choose Our Forage Gas Relief Valve
- One‑Way Oxygen Control Releases excess CO₂ while preventing oxygen from re‑entering the bag — helping protect silage from heating and surface spoilage.
- Optimized Pressure Setting Holds ~½ lb of pressure to push oxygen out naturally before venting, supporting a more consistent anaerobic environment.
- Side‑Venting 2.5 Model The 2.5 design vents from the sides to keep out debris and rain, and it seals better for reliable performance during gassing periods.
- Integrated Installer Tool Built‑in tool simplifies installation and helps you place the valve correctly and consistently.
- Durable & Reusable Designed for repeated seasonal use with proper handling and storage.
