1、Operation Instruction: Use a bypass valve to allow excess gas to leave the receiving drum while the silo is conveying under pressure. Helps you achieve slow, controlled and pressurized delivery. 2、Release Keg Pressure: Mini CO2 gas regulator can also be used to release pressure from the keg during filling or filtration. The pressure relief valve can be adjusted to relieve pressure. 3、Applicable Scenes: The basic no frills relief valve is perfect for brewing in high traffic restaurants or individual home brews. Impressive premium replacement for old part. 4、Dry Under Pressure: This allows you to dry the hops earlier while reducing oxygenation. Active yeasts are more likely to metabolize the oxygen introduced during dry hops during active fermentation. Since carbon dioxide is not expelled from the beer as violently as it is under pressure, desired compounds, flavors and aromas are more likely to remain in the beer under pressure. 5、Stainless Steel Material: Beer keg pressure regulator is made of stainless steel material, anti rust and durable. Naturally and accurately carbonate beer directly in the keg.
