2404-2 - Excess pressure valve with pilot valve for small set point ranges

The pilot operated Type 2404-2 excess pressure valve is preferably used for the precise control of inert gas in tank blanketing applications. It regulates the excess pressure of the inert gas to a constant pressure within the millibar range. The inert gas (usually nitrogen) is applied to protect the product inside the tank from reacting with the ambient atmosphere. In this way, the safe operation of tanks is achieved by allowing the tank to “breathe” in a controlled manner. Additional benefits include reduced pollution and inert gas costs.

The pressure regulator ensures that the blanketing pressure in the tank remains constant while the tank is being filled. Furthermore, adverse weather conditions, e.g. direct sunlight, can affect the pressure inside the tank. In this case, the excess pressure valve equalizes the tank pressure, resulting in stable pressure conditions.
