China Flange Type Triple Offset Butterfly 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® 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.
