ASTM B62 StandardMaterial Specifications• Bronze Composition: ASTM B62 specifies the composition of bronze materials used in valve manufacturing.

In the industrial field, ANSI 150LB bronze butterfly valves are widely used. Dimensional tolerances and fluid compatibility in its design specifications are two key aspects, which will be analyzed in detail below.

I. Common Material Types and Performance Parameters of Bronze Butterfly Valves


The common material types of bronze butterfly valves mainly include nickel-aluminum bronze, aluminum bronze, and cast iron, etc. Among them, nickel-aluminum bronze is a relatively common choice due to its excellent corrosion resistance, especially suitable for seawater environments. Aluminum bronze is also widely used in the industrial field because of its good corrosion resistance and wear resistance.


In terms of performance parameters, bronze butterfly valves usually have the following characteristics:

I. Introduction
In the industrial field, bronze butterfly valves are widely used, and their leakage rate is one of the key indicators for measuring the performance of valves. Different international standards have their own regulations for the leakage rate testing of butterfly valves. Among them, API 598 and ISO 5208 are two commonly used standards. Understanding the differences in their pressure curves helps to evaluate the quality and performance of bronze butterfly valves more accurately. This article will conduct a comparative analysis on this aspect.
