Stainless Steel Sanitary Grade In-line Type Quick Release Safety Valve

The safety valve is used to used to keep the set pressure in the system. The sanitary safety valve plays a role of safety protection in the system. When the system pressure exceeds the specified value, the sanitary safety valve opens to discharge part of the gas/fluid in the system into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.

The safety valve is used to used to keep the set pressure in the system. When the system pressure is higher than set pressure, valve open to reduce the pressure, so it also named pressure relief valve or pressure release valve.

Before the valve is dispatched, we have set the pressure to given value. If needed, a pressure gauge needs to be installed before the inlet of safety valve.


The sanitary safety relief (release) valves are widely used for food, beverage, dairy, pharmacy, chemical or any food processing industries

Working Principle

This safety valve is a self-control valve relying on medium pressure. A specific pressure is calibrated by adjusting the compression spring of the regulating cover and the lock nut. The calibrated pressure is the maximum safe pressure value which set to avoid damage to the pipeline equipment. When the pipeline pressure exceeds the set pressure , the valve seat will automatically open, the medium is discharged and the pressure in the pipeline system is released to protect the pipeline and equipment. When the pressure of pipeline returns to the normal value, the valve seat will be forced automatically to push back, finally valve automatically closes.
