Pressure Relief Valve Sizing

Pressure Relief Valve Sizing Craig Spears November 10, 2015. Pressure relief valves are used to protect equipment from excessive overpressure. Properly sized relief valves will provide the required protection, while also avoiding issues with excessive flow rates, including: possible valve damage, impaired performance, undersized discharge piping and effluent handling systems, and higher costs.
