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.

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®️ 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.

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.
