China Metal Seated Triple Offset Butterfly 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® 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®️ Trunnion mounted ball valve as a high-performance product that meets international standards like API-6A, API-6D, ASME-B16.34, ISO-17292 and more. LYV®️ Trunnion mounted ball valve has obtained API-6FA fire certification, which prove product has capacity to use for various fire safe requested applications. LYV®️ as a manufacturer to produce trunnion mounted ball valve can manufacturing NPS 2” to NPS 48” trunnion mounted ball valve, maximum pressure rating can reach to 2500LB. Furthermore, LYV®️ has conditions and experience to produce low-temperature trunnion mounted ball valve. Contact our sales for more information.

LYV®️ adopt double offset design in the resilient seated butterfly valve. The double offset design can reduce the compression between seal ring and seats during valve operating. Improve the service life of the valve. LYV®️ double offset resilient seated butterfly valve has a nickel alloy welded overlaid on body seat. This design makes the valve have low friction coefficient when valve open and close.

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.
