​At 9:30 a.m. on September 18, 2025, the J - VALVES team set off from the company and went to the cinema to watch the movie "Unit 731" with a sense of awe and remembrance for history.

The implementation mechanism of rapid cutoff. Rotary motion and sealing principleThe operation of the ball valve is realized by rotating the valve core. When the valve core rotates 90 degrees, the hole of the valve core is aligned with the axis of the pipeline, and the fluid can pass through smoothl

working principleBall ValveThe core component of a ball valve is a sphere with a central hole. The fluid is cut off and opened by rotating the sphere 90 degrees. The sphere is installed in the valve body and closely cooperates with the valve seat to form a seal. When the hole of the sphere is aligne

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.

Design Features(1) 3-Piece StructureThe 3-piece structure is one of the prominent features of the 3-Piece Forged Steel Ball Valve (900#). This structure divides the valve body into three parts, which are connected by bolts. Such a design not only facilitates the assembly and maintenance of the valve

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. 

I. Product OverviewThe J-VALVES top-entry ball valves are meticulously crafted from high-quality materials. They feature a compact structure, are convenient to operate, and possess excellent sealing performance. With their unique top-entry design, they are easy to maintain and repair, and are widely

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 industrial fields such as petroleum, natural gas, chemical engineering, and petrochemicals, the fire safety design of industrial valves is of vital importance. Once extreme situations like fires occur, whether the valves can maintain their sealing performance and normal operating functions under

In numerous industrial fields, valves, as crucial fluid control equipment, have their performance and quality directly related to the stable operation and safety of the system. J-VALVES American Standard Duplex Steel Flange Ball Valves, with their outstanding performance and wide applicability, have

Overview of the Standards1. API 6D: Pipeline and Pipeline ValvesAPI 6D is a standard developed by the American Petroleum Institute (API) specifically for pipeline valves used in petroleum and natural gas systems. It focuses on gate, ball, check, and plug valves and is designed to address the unique

In various industrial and civil pipeline systems, ball valves can be seen everywhere. With many advantages such as simple operation and excellent sealing performance, they play a vital role in numerous fields like petroleum, chemical engineering, gas, water supply and drainage. However, there are a

In fields such as energy and chemical engineering, and oil and gas transportation, high-pressure fluid control has always been a core challenge.
