Understanding Valve Pressure-Temperature Ratings

ASME B16.34: Understanding Valve Pressure-Temperature Ratings

“Class 800” is a familiar term, but it only tells half the story. The true safety of an industrial valve is defined by its Pressure-Temperature (P-T) rating, governed by the ASME B16.34 standard. As process temperatures climb, the allowable pressure capacity of even the highest-grade steel drops. This guide breaks down the science of P-T ratings, helping engineers prevent catastrophic failures by selecting the right valve for the right thermal environment.

Forged vs. Cast Steel Valves: The Definitive Engineering Guide

Forged vs. Cast Steel Valves: The Definitive Engineering Guide

In high-pressure and high-temperature environments, the manufacturing process of a valve body is just as important as the alloy itself. While cast valves offer versatility for large-bore systems, forged steel valves provide superior molecular density and structural reliability for critical lines. This guide breaks down the engineering differences between forging and casting to help you select the right valve for your system’s safety and longevity.
