Pressure Reducing Valve in India

A Pressure Reducing Valve (PRV) is a self-operating device designed to maintain a steady downstream or upstream pressure within a system. Its primary role is to reduce higher inlet pressure to a stable, lower outlet pressure that is safe for equipment and processes. These valves are commonly used across industries such as water supply, steam distribution, and oil & gas applications. In steam systems, a pressure reducing valve functions by balancing steam pressure against the force of an internal spring, ensuring consistent regulation. This fundamental principle forms the basis of most modern PRV designs. Depending on how the valve opening is controlled, pressure reducing valves are generally divided into two main categories.
