These precision-engineered spunding valves are constructed from corrosion-resistant 304 stainless steel, ensuring long-term durability and sanitary performance in demanding fermentation environments. Designed for pressure fermentation and natural carbonation, they allow brewers to set and maintain specific pressure thresholds (typically adjustable from 0–30 PSI), automatically venting excess CO₂ to prevent over-pressurization.
The valve features a spring-loaded adjustable pressure release mechanism, a barbed or threaded gas inlet, and an integrated pressure gauge for real-time monitoring. Ideal for closed fermentation systems, unitanks, and keg conditioning, these valves help improve carbonation consistency, reduce oxygen exposure, and streamline transfer operations.
