In LNG systems, a valve must do more than open and close. It must perform reliably in extreme low-temperature conditions while keeping tight sealing and safe operation.A standard ball valve may work well in normal industrial service, but when the temperature drops to -196°C, common problems become m

What is the difference between CE certification and API 6D certification for large diameter trunnion ball valves? This article compares their standards, application scope, sealing performance, and suitability for oil transportation projects in a clear and practical way.

Grasp the core differences between ASME B16.34 and API 600 certifications for 6-inch 150LB WCB flanged gate valves under high-pressure working conditions. Master key distinctions including wall thickness, testing standards and material requirements via detailed comparison tables, helping you select proper valve standards and ensure project safety.

In petrochemical high-temperature systems, a valve is never just a simple mechanical part. For a 12" 300LB A105N forged steel flange globe valve, sealing stability often determines whether the system runs safely, whether shutdowns happen, and how often maintenance is needed.Many buyers notice that t

This article uses a simple comparison table and clear language to explain why an API6D certified DN400 PN63 09Г2C trunnion ball valve is more impact resistant than a standard ball valve in high pressure natural gas stations.

Learn how trunnion ball valves support nuclear power auxiliary systems with seismic resistance, tight shutoff, and ASME nuclear-grade design principles for safe, long-term performance.

This page helps engineers, buyers, and project teams compare API 6D vs API 608 for trunnion ball valves, with a clear focus on scope, application, end connections, pressure classes, and practical selection guidance for pipeline, refining, and industrial projects.

In industrial piping systems, with the continuous increase of pipe diameters and pressure ratings, the selection of ball valve structural forms becomes particularly critical. While floating ball valves are widely used in small-diameter working conditions, trunnion ball valves are often a more reliable and mature solution for large-diameter, high-pressure systems.

In steam systems, the selection of valves is crucial for the safe and efficient operation of the systems. The BS 1873 standard provides important technical guidance for the design and operation of steam systems. 

As is known to all, in the field of LNG (liquefied natural gas) low-temperature applications, the selection and design of valves are of crucial importance, because they need to stably maintain reliable sealing performance and ensure operational stability in the harsh low-temperature environment. The
