What are Pressure-Reducing Regulators?

A pressure reducing regulator reduces a high source pressure (e.g. an inlet pressure of 3000 psig / 207 bar) to a lower working pressure (e.g. an outlet pressure of 100 psig / 6.9 bar) that is suitable for an application. The regulator will attempt to control the outlet pressure within acceptable limits as other conditions of the gas or liquid such as temperature, pressure and flow.

Types of pressure control instruments

Pressure regulator applications:

Pressure regulators are used to reduce pressure in variety of applications like: Air, Nitrogen, Hydrogen, Oxygen, Hydrocarbons in liquid or gas phase. NACE compliant pressure regulators in gas and oil applications. Pressure regulator applications include sample systems, over pressure protection for pumps, Differential pressure for mechanical seal systems, compressor stations, air header lines, vacuum breakers, tank blanketing regulators, steam regulators, mechanical seal systems for the supply of seal gas for rotating equipment, utilities, pressure pumps, sump pumps, wash-down stations, and injection lines.
