Comparison of durability between stainless steel and carbon steel floating ball valves, detailed CE certification (EN 16668:2025) compliance requirements, material characteristics and application scenarios, helping you avoid mistakes and choose cost-effective floating ball valves meeting EU standards.

This 2-inch floating ball valve features an ASTM A216 WCB carbon steel body, a Class 150 pressure rating, RF flanged connection, and complies with API 607 fire-safe requirements. It delivers an optimal balance of economy, durability and safety, making it a common and practical valve solution for numerous industrial projects.

Understanding Floating Flanged Ball ValvesFloating flanged ball valves, a staple in the realm of quarter-turn valves, employ a spherical ball mechanism to regulate fluid flow. What sets them apart is the unique floating design of the ball, which is supported by the valve seats. Under pressure, this

In modern industrial piping systems, large-diameter ball valves not only perform on-off functions but also are directly related to the operational safety, sealing reliability and long-term stability of the system. Especially in occasions involving high temperature, fire hazards or complex working conditions, the safety design of valves is particularly critical.

1. Understanding Pressure Ratings (PN16 to PN100)The pressure rating of a floating flange ball valve is expressed in PN, where PN16 indicates a valve rated for 16 bar (or approximately 232 psi) and PN100 indicates a valve rated for 100 bar (or approximately 1450 psi). These ratings are determined by

Ball valves, as an important type of industrial valve, are widely used in fields such as petroleum, natural gas, chemical engineering, and power. With the continuous development of industrial technology, the performance requirements for ball valves are getting higher and higher, especially under ext
