China Casting Trunnion Ball Valve Manufacturer, Supplier, Factory

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 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®️ is a professional China DBB Inject Ball Valve manufacturer. This is a special type of ball valve that integrates the dual-blocking and venting (DBB) functions. It is specifically designed for critical operating conditions where dual isolation, intermediate chamber pressure relief, and fluid injection need to be achieved within a single volume. This DBB Injection Ball Valve is a key equipment used in the process industries such as oil, gas, and chemicals for safety maintenance, instrument calibration, and chemical agent addition.

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® is a leading China quality Reduced Bore Ball Valve supplier. This valve is a High Performance Reduced Bore Ball Valve specially designed for precise control of small flow rates. This Reduced Port Ball Valve achieves more precise regulation and shut-off of fluids through a unique structure where the diameter of the ball is smaller than that of the pipe. It combines the advantage of rapid opening and closing of ball valves with the control ability of needle valves, and is an indispensable key component in instruments and meters, experimental devices, and fine chemical processes.
