In heavy industries such as coal chemical, polysilicon, and petrochemical production, valves, as core pipeline control equipment, directly determine the operating efficiency of the production line. Traditional wear-resistant ball valves and imported track ball valves have long faced problems such as media erosion, valve cavity jamming, valve body seizure, and short service life. Frequent replacements […]
The side-mounted ultra-low temperature online maintainable ball valve is designed by Teji Valve Group by combining the advantages of three-piece ball valves and top-mounted ball valves. Its structure is novel and unique, easy to install, and allows for online maintenance. The valve’s design and production are not limited by structure and can be designed according to user […]
The A105 forged steel 600LB high-pressure large-diameter soft-seal ball valve, independently developed and manufactured by Teji Valve Group, has completed production testing and is officially shipped, contributing to the safe and stable operation of oil, gas, and chemical pipelines. 01 Teji Valve 600LB High-Pressure Soft-Seal Ball Valve Completes Production Testing Suitable for various harsh operating conditions […]
Valve Material Requirements Due to the presence of oil-coal slurry in the direct coal liquefaction reaction, the wear and tear on valves, pipelines, and other equipment materials caused by the coal slurry must be considered. Therefore, the materials used to manufacture valves must possess comprehensive performance that meets the usage requirements. Specifically, they should have: […]
With increasing global awareness of environmental pollution in recent years, countries and the world are striving to develop clean energy to gradually replace polluting traditional energy sources, providing impetus for development. In particular, liquefied natural gas (LNG) and liquefied petroleum gas (LPG) are rapidly emerging as new energy sources worldwide. This has led to the […]
The high-performance compensated shear valve is a patented product specially developed for demanding working conditions. It has replaced traditional wear-resistant ball valves in the coal chemical and polysilicon industries, resolving issues such as sticking, seizure, and erosion during valve application. In the petrochemical field for heavy oil and residue oil, it has replaced imported trunnion […]
