LYV®️ is a professional China quality BW End Trunnion Mounted Ball Valve manufacturer. This is a highly reliable valves designed to cope with harsh industrial environments. This Butt Weld End Trunnion Mounted Ball Valve adopts butt welding connection to ensure permanent sealing and effectively resolves pipeline stress through a unique end support structure. It is specifically designed to provide a lifetime stable control solution for critical pipelines such as large-diameter, high-temperature and high-pressure, and long-distance transportation.

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® is a professional China Fully Welded Ball Valve manufacturer The valve body of this type is completely welded without bolted connection. As a result, the all-welded body ball valve provides excellent sealing performance with virtually no external leakage, making it particularly suitable for piping systems where safety and reliability are highly required.
