sanitary safety valve

Applications
AQ3 sanitary safety valve is a sanitary stainless steel safety valve, with safety design for equipment protection. It is installed in the discharge pressure loop in order to protect pipelines, pumps, fittings, and tanks, etc.. It is widely used in food, beverage, diary, pharmaceutical and beer industries.

Operating Principle
AQ3 sanitary safety valve calibrates a specific pressure by adjusting the gland nut of the spring. Calibration pressure is a maximum safe pressure value fixed in order to avoid equipment damage. Under normal working pressure, the valve is closed. When the pressure in the pipe system exceeds the calibration pressure, the valve is open. Thus, the pressure in the pipe system is discharged and the pipeline and equipment are protected.

AQ3 sanitary safety valve is operated by a handle. AQ3-1 series is an improved version of the AQ3 sanitary safety valve. It is equipped with a pneumatic actuator, which is convenient to carry out CIP cleaning to safety valve and pipelines.

AQ3 sanitary safety valve is a more specialized valve, and it has been checked strictly before delivery. In order to ensure conformity to the actual operation conditions, please check the valve on-site if possible.
