Instrument Pressure Regulators
In vessels, reactors, centrifuges, or stirred vessels in the process industry, liquids are often blanketed with an inert gas atmosphere to prevent oxidation, contamination, or to ensure explosion protection.
Depending on the application and requirements, various regulators in corrosion-resistant materials are used for pressures ranging from 1 mbar to 20 bar. These are mainly self-acting mechanical regulators that operate independently of auxiliary energy, such as pressure regulators for reduction, excess pressure, differential pressure, and negative pressure, as well as breather vents for positive and negative pressure.
