Gas-Over-Oil Full Welded Ball Valve

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.

Forged Ball Valve

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.
