How it works
During normal homogenizer operations the pneumatic overpressure relief valve works as a standard spring loaded relief valve: it is closed and it opens when product side pressure is higher than calibration pressure.
Possible working conditions are:
- Normal working condition. The product side pressure is lower than safety valve calibration pressure: the safety valve remains in closed position.
- Overpressure condition. The product side pressure is higher than calibration pressure: the safety valve opens.
- CIP condition. The product side pressure is lower than safety valve calibration pressure: the safety valve is in closed position and it can be opened by removing air.
Main advantages
- The spring loaded system allows immediate valve opening in case of overpressure
- Valve calibration is precise and reliable
- Auxiliary systems to control valve opening in case of overpressure are not needed
- The design of the valve doesn’t compromise safety also in case of safety valve failure (valve opening at lower pressure in case of valve components failure)
In order to clean internal surfaces of the safety valve, during CIP it is possible to open the valve by supplying air to the pneumatic actuator. All parts connections in contact with the product have gaskets to avoid metal-to-metal surfaces contact and consequently to increase safety valve cleanability.
The pneumatic safety valve has been designed with same process connection used in standard safety valve, therefore it can be installed as retrofit without any machine modification.
Reimagine liquids
It may surprise you how many products need homogenization in their manufacturing process to make them more compatible with your daily life. Stabilization and a longer shelf life have always been among the highest priorities in many different processing industries but, especially nowadays, as lifestyles continue to change rapidly, they are becoming more and more valued.

Making milk production more sustainable for a growing world
The world's population is growing and with it demand for milk. Dairy is an essential component of many global diets. However, its production can be resource-intensive and impact the environment. GEA’s Christian Müller, Senior Director Sustainability Farm Technologies, sheds light on how technological innovations powered by GEA make milk production more efficient and profitable.
