China Reduced Trunnion Bore Ball Valve Manufacturer, Supplier, Factory

LYV® dual-plate check valves are designed to be robust, reliable, high performing and aesthetically pleasing. We are committed to improving our manufacturing processes and using stringent quality control measures to ensure that our check valves surpass their peers in quality.

LYV® gate valves are designed to be high performance. We invest heavily in refining our manufacturing processes and implementing stringent quality control measures to ensure that our high pressure gate valves stand out for their superior quality and durability in comparison to their counterparts.

LYV®️ large DN size oxygen ball valve is a special valve specially designed for oxygen pipe network, which is widely used in the pipe network of steel, metallurgy, petrochemical, chemical and other oxygen-using projects. In addition to the functions of ordinary valves, it also has its own characteristics such as good flame retardancy, good electrical conductivity, fast heat transfer, compact structure, oil resistance, safety and reliability. Strict oil prohibition measures are adopted during manufacturing, and all parts are subjected to strict degreasing treatment before installation. All diameter valves are equipped with conductive screw holes at the flange ends to prevent static electricity. The exposed parts of the valve have protective measures to prevent dust and oil pollution. With the valve seat of the metallurgical industry, the special oxygen ball valve and the special oxygen stop valve are widely used in steel, medicine, chemical and other industries.

As a type of Ball valve, the DBB double block and bleed ball valve uses the Trunnion mounted as the sealing structure. The valve actuated by Worm gear, and uses carbon steel as body material.

LYV®️ Gas-over-oil actuated BW ends ball valve can meet standards such as API, DIN. Produce size range from NPS2 inch up to 24 inch, DN50 to DN600.

LYV®️ BW end trunnion mounted ball valve as a high-performance product that meets international standards like API-6A, API-6D, ASME-B16.34, ISO-17292 and more.
