China Double Flanged Triple Offset Butterfly Valve Manufacturer, Supplier, Factory

LYV® swing 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® High performance butterfly valve adopt double offset disc with floating seat design, can withstand pressure comes from both sides of pipeline and keeping its excellent sealing performance. LYV®️ High performance butterfly valves are available for wafer, flanged and lug style end connections.

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® fully welded ball valves are precisely engineered to ensure superior quality and performance. Our stringent manufacturing processes and quality control measures result in products that outperform similar offerings in the industry. In addition, they fulfil the fire protection criteria outlined in API 6FA and are appropriate for a diverse range of applications that necessitate fire protection.

The electric actuated plunger valve is a new multifunctional valve suitable for urban water supply, industrial water supply, mining water use, power plants, and water diversion projects in pipeline systems.

LYV®️ Forged ball valve refers to a valve that uses the process of forged steel. In fact, the difference is in material, forged steel valves are often used in high temperature and high pressure conditions. There are commonly forged steel gate valves, forging steel globe valves, forged steel check valves, forged steel ball valves and so on. Forged valves are usually suitable for small size valves, with a range of 1/2” ~ 4″and pressure ranges of 150LB ~ 4500LB.
