China Pneumatic Ball Valve Manufacturer, Supplier, Factory

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.

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®️ 1500LB Globe valve can meet standards such as API, DIN, ISO, GOST, GB, JIS. Produce size range from NPS10 inch up to 10 inch , DN250 to DN250. Pressure rating covers ANSI Class1500LB and PN250.

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® 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.

The slow acting check valve also called as slow closing valve, is designed for water supply, air conditioning, and fire protection piping systems, suitable for water as the medium with a temperature up to 80°C.
