China Multi-layer Sealing Butterfly 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® butt welded metal to metal butterfly valve features a unique U-shaped replaceable seat design, which provides a reliable seal against the compression of the elastic seat when closed by the disc. And providing a zero leakage seal at bi-directional pressure.

Pressure reducing valve is a valve that reduces the pressure to a required outlet pressure through adjustment and relies on the energy of the medium itself to automatically keep the outlet pressure stable. From the perspective of fluid mechanics, the pressure reducing valve is a throttling element with variable local resistance.

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®️ large DN size oxygen ball valve is a special valve specially designed for oxygen pipe network, which is widely used in the pipe network of steel, metallurgy, petrochemical, chemical and other oxygen-using projects. In addition to the functions of ordinary valves, it also has its own characteristics such as good flame retardancy, good electrical conductivity, fast heat transfer, compact structure, oil resistance, safety and reliability. Strict oil prohibition measures are adopted during manufacturing, and all parts are subjected to strict degreasing treatment before installation. All diameter valves are equipped with conductive screw holes at the flange ends to prevent static electricity. The exposed parts of the valve have protective measures to prevent dust and oil pollution. With the valve seat of the metallurgical industry, the special oxygen ball valve and the special oxygen stop valve are widely used in steel, medicine, chemical and other industries.

LYV® Concentric Butterfly valve is manufactured to the highest standards, backed by our commitment to quality and excellence. We use advanced manufacturing processes and rigorous quality control to ensure each valve meets or exceeds industry benchmarks. Our valves are of exceptional quality, surpassing similar products in the industry in terms of durability, performance, and reliability.
