Ball Lock Spunding Valve – 0–30 PSI Gauge

Compact adjustable pressure relief valve with a ball lock quick disconnect, integrated 0–30 PSI gauge, and manual pull ring. Use on a compatible pressure-rated fermenter or keg to vent excess CO2 during pressure fermentation while retaining pressure for natural carbonation. It can also vent the receiving keg during closed pressure transfers. Rotate the black cap to adjust pressure relief, or use the pull ring to vent manually. Stay within the vessel’s pressure rating and retain its required safety relief valve.
