China Epdm Lined Concentric Butterfly Valve Manufacturer, Supplier, Factory

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.

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.

As a type of Ball valve, the DBB double block and bleed ball valve uses the Trunnion mounted as the sealing structure. The valve actuated by Worm gear, and uses carbon steel as body material.

LYV® aluminum bronze 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®️ Triple offset butterfly valve are manufactured with high standard. We control the quality of the casting to make valves far superior to similar products in the industry. LYV®️ Triple offset butterfly valve use high quality metal + graphite multi-layer sealing ring, which enables the valve to be used under high pressure and high temperature conditions.

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.
