Pressure relief valves (PRVs) provide critical overpressure protection in many industries by venting excess process media when necessary. PRVs often include bellows in applications with relief valve headers subject to backpressure, but bellows may be damaged by cycling or corrosive chemical applications, causing significant performance impacts and environmental leakage that may go unnoticed for years.
This article discusses a recently introduced PRV design that replaces bellows with a balanced diaphragm. This new balancing technology can be installed as an upgrade to standard bellows PRVs, and it extends backpressure limits while providing greater flow capacity than a similarly sized balanced bellows PRV.
