China Casting Trunnion Ball Valve Manufacturer, Supplier, Factory

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.

LYV® gate valves are meticulously engineered to embody robustness, reliability, high performance, and aesthetic appeal. We invest heavily in refining our manufacturing processes and implementing stringent quality control measures to ensure that our gate valves stand out for their superior quality and durability in comparison to their counterparts.

LYV®️ adopt double offset design in the resilient seated butterfly valve. The double offset design can reduce the compression between seal ring and seats during valve operating. Improve the service life of the valve. LYV®️ double offset resilient seated butterfly valve has a nickel alloy welded overlaid on body seat. This design makes the valve have low friction coefficient when valve open and close.

LYV® aluminum bronze gate valve has been carefully designed to reliability and high performance. We invest heavily in refining our manufacturing processes and implementing stringent quality control measures to ensure that our aluminum bronze gate valves stand out for their superior quality and durability in comparison to their counterparts.
