​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.

Floating ball valves are versatile and reliable components used to control the flow of fluids in various industrial applications. Their robust design, ease of operation, and ability to provide a tight seal make them ideal for a wide range of industries. This article explores the diverse applications

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 booming oil-brushing art industry in Nigeria, there are stringent requirements for the performance and quality of various industrial equipment. The DN15 PN550 A105 floating ball valve provided by the J-VALVES team, with its outstanding quality and performance, has become the preferred valve product for numerous oil-brushing art enterprises.
