304 Stainless Steel Pressure Valve
Sanitary Stainless Steel Air Pressure Relief Safety Valve：The valve controls the pressure by adjusting the spring. When the pressure in the tank is bigger than the valve setting pressure, the valve seat automatically turns on, the pressure in the equipment system is released, and the beer fermentation is effectively processed. The tank is no more in high pressure, which may cause danger. The pressure can be set according to the user's need. The valve has a glass, which can be filled with water. It can be seen when gas comes out. A spare pressure gauge can be available.
