In many high-temperature and high-pressure scenarios in industrial production, the choice of butterfly valves is quite an important matter. Today, let's make a good comparison between bronze butterfly valves and stainless steel butterfly valves to see what the differences are in terms of material performance and standard adaptability.

In today's highly competitive industrial valve market, the bronze butterfly valves manufactured by J-VALVES in China stand out and attract much attention. What unique aspects enable them to demonstrate strong market competitiveness among numerous valve products? Let's explore this in depth.

Understanding API and ANSI StandardsAPI StandardAPI 609 is a widely recognized standard that specifies the requirements for butterfly valves, including design, materials, testing, and marking. Compliance with API 609 ensures that the valves meet stringent quality and safety standards, making them su

It specifies the design, manufacturing, and testing requirements to ensure reliability and safety.• Material Specifications: API

In ship systems, bronze butterfly valves play an indispensable role, especially those with a caliber in the range of DN80 - DN300. Understanding the key points for their selection and the adaptation schemes to MARPOL standards is crucial for ensuring the normal operation of ship systems and meeting environmental protection requirements. The following is a detailed introduction for you.

In the field of industrial fluid control, wafer-type butterfly valves play a crucial role, and different design standards often determine their quality and performance. As a brand that has attracted much attention in the industry, J-VALVES' products follow a variety of design standards. Now, let's compare these design standards in detail to help you gain an in-depth understanding of the key factors behind quality assurance.

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.
