2406 - Excess pressure regulator (flanged)

The Type 2406 self-operated excess pressure regulator is used to control the pressure of flammable gases used as a source of energy, e.g. in boilers, driers, vaporizers, heat exchangers, or industrial furnaces. Alternatively, it can control the compressed air supply in process engineering applications.

An additional application of the regulator is the pressure control of inert gas used for inerting or blanketing reaction or storage tanks to protect the product in the tank from oxidation, explosion, or escaping. To achieve economical consumption of the inert gas, its pressure must be controlled to always remain slightly higher than atmospheric pressure while the tank is being filled or emptied.

An excess pressure valve is used to control the upstream pressure (p1) to an adjusted set point. The design of an excess pressure regulator valve is to open when the upstream pressure rises above the set value.
