In the field of industrial pipeline systems, especially in the petroleum, natural gas, and large-scale water treatment industries, large size trunnion ball valves that comply with API 6D standards have become the core equipment for fluid control and isolation. API 6D, formulated by the American Petroleum Institute (API), is a globally recognized authoritative standard for pipeline valves, defining strict requirements for the design, manufacturing, assembly, testing, and documentation of valves. For large-diameter pipeline projects, the stability, pressure-bearing capacity, and sealing performance of valves directly affect the safety and efficiency of the entire system.

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 modern industrial production, fluid control is a key link to ensure the smooth progress of the production process. As an efficient and reliable fluid control device, the ear trunnion ball valve is widely used in multiple fields such as petroleum, chemical engineering, natural gas and water treatm

In the field of industrial valves, it has always been the goal of J-VALVES to provide high-quality products that match the working conditions of customers around the world. Recently, a batch of 10" 150LB CF8M trunnion mounted ball valve were successfully shipped to Canada, helping to promote the local industrial projects efficiently. This case has also become another model for J-VALVES to serve the global market.

This valve, designed for precision and durability, adheres to a multitude of international certifications and standards that guarantee its performance and quality.

In high-risk industries such as petroleum, natural gas, and chemical engineering, the fire resistance of valves is of crucial importance. As a widely used type of valve, the fire safety certification of J-VALVES ball valves is a key aspect in ensuring the safety of equipment and personnel. This arti

In the procurement of industrial valves, it is crucial to ensure the quality and performance of valves. The API 598 standard provides clear guidance for the inspection and testing of valves, helping purchasers make informed decisions when choosing TRUNNION BALL VALVES, GATE VALVES and BUTTERFLY VALVES. This article will compare in detail the API 598 testing costs and acceptance procedures of these three types of valves to help you better understand and choose suitable valve products.
 

In industrial application scenarios with high temperature and high pressure, the selection of valves is of crucial importance. As two common types of valves, trunnion ball valves and gate valves have significant differences in their pressure ratings under the ASME B16.34 standard.
