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

Floating ball valves​ made from C95800 (Copper Alloy) are widely used in industrial piping systems due to their excellent corrosion resistance, thermal conductivity, and durability. One of the key design considerations for these valves is the pressure rating, which determines the safe operating limits under various temperature and fluid conditions. Understanding how ANSI and API standards guide pressure rating selection is critical for ensuring system safety and performance.

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.

What Makes A105 Hydraulic Ball Valve Product Range More Stable in High Pressure SystemsIn high pressure systems, valve stability is not just a technical detail. It directly affects safety, uptime, maintenance cost, and overall system performance. For oil and gas lines, hydraulic circuits, chemical t

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.

Gate valves are ideal for low pressure drop, large-diameter, and on-off service, while globe valves are better for precise flow control in small-diameter lines. This article compares structure, performance, applications, and selection tips.

Are corrosive fluids shortening valve life? Discover why carbon steel valves fail early and how stainless steel high-pressure ball valves deliver stronger corrosion resistance, better sealing, and longer service life in chemical, offshore, and high-pressure applications.

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

The J-VALVES High Pressure Ball Valve with Metal Seated Technology is specifically engineered to address these challenges by delivering superior leakage prevention, durability, and operational reliability.

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.

On the evening of January 31st, bathed in bright and warm lights, the 2025 J-VALVES Annual Gala with the theme On the Road, Heading for the World kicked off in grand style! All members of the J-VALVES family gathered together, shedding the toil and weariness of the whole year, and carrying our gains and honors. We looked back on our journey side by side amid laughter and joy, and marched toward a brand-new future with united striving, sharing this exclusive reunion feast and pledge of progress that belongs to us all.
 

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

In modern industrial pipeline network systems, fluid control often faces pain points such as insufficient corrosion resistance, inflexible flow direction switching, and difficulty in ensuring long-term reliability. So, can enterprises find a 4-way ball valve that combines durability, flexibility, and intelligent compatibility? The J-VALVES Aluminum Bronze 4-Way Ball Valve may be the key to solving this problem.

​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
