China Trunnion Ball Valve Manufacturer, Supplier, Factory

LYV®️ Gas over oil actuated ball valve through a self-actuating actuator. By the pressure of the medium of the pipeline itself to actuate valve open and close. The product directly use natural gas inside of the pipeline as the air supply of pneumatic. The whole system design for high pressure. Through air supply filtering process without decompression.

LYV® Reduced Bore Ball Valve is designed to provide superior quality and performance. Our engineering team implements strict quality control measures to ensure that our ball valves offer durability and quality that surpasses competing products. We use advanced manufacturing processes and stringent quality control measures to ensure that every valve meets the international standards.

LYV® Concentric Butterfly valve is manufactured to the highest standards, backed by our commitment to quality and excellence. We use advanced manufacturing processes and rigorous quality control to ensure each valve meets or exceeds industry benchmarks. Our valves are of exceptional quality, surpassing similar products in the industry in terms of durability, performance, and reliability.

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®️ Gas-over-oil full welded ball valve through a self-actuating actuator. By the pressure of the medium of the pipeline itself to actuate valve open and close. The product directly use natural gas inside of the pipeline as the air supply of pneumatic. The whole system design for high pressure. Through air supply filtering process without decompression. The gas directly into the gas tank and high-pressure control valve components. Under the action of the control signal, the high-pressure controlled gas enters the corresponding gas/liquid circuit. And by the principle of isobaric transmission of the liquid medium to realize the gas/liquid synchronous transmission, acting on the hydraulic cylinder of the valve drive device and controlling the valve.

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.
