China Forged Trunnion Ball Valve Manufacturer, Supplier, Factory

LYV®️ as a cryogenic ball valve supplier, our valve features API 6D certification, a 6-inch size, 900 LB capacity, DN150 diameter, and PN150 pressure rating. Made from high-quality stainless steel and conforming to ASTM A182 F316 standards, it features a lever, gearbox, and electric operation. The valve also features RF flanged ends for easy installation and access.

LYV® floating ball valves are meticulously engineered to ensure superior quality and performance. Our stringent manufacturing processes and quality control measures result in products that outshine similar offerings in the industry. These floating ball valves meet multiple international standards such as API-6A, API-6D, ASME-B16.34, and ISO-17292. Additionally, they have obtained the API-6FA fire certification, making them suitable for applications requiring fire safety.

LYV® High performance butterfly valve adopt double offset disc with floating seat design, can withstand pressure comes from both sides of pipeline and keeping its excellent sealing performance. LYV®️ High performance butterfly valves are available for wafer, flanged and lug style end connections.

LYV®️ Forged ball valve refers to a valve that uses the process of forged steel. In fact, the difference is in material, forged steel valves are often used in high temperature and high pressure conditions. There are commonly forged steel gate valves, forging steel globe valves, forged steel check valves, forged steel ball valves and so on. Forged valves are usually suitable for small size valves, with a range of 1/2” ~ 4″and pressure ranges of 150LB ~ 4500LB.

LYV® gate valves are designed to be reliable and high performing. We focus a lot on improving our manufacturing processes and strict quality control to ensure our gate valves are of the highest quality and durability compared to others.

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.
