China Pneumatic Ball Valve Manufacturer, Supplier, Factory

LYV®️ Long shaft underground BW ends ball valve can meet standards such as API, DIN. Produce size range from NPS2 inch up to 24 inch, DN50 to DN600. Pressure rating covers ANSI Class150LB, 300LB, 600LB and PN10,PN16,PN25,PN40,PN64,PN100.

LYV® is a China quality High Pressure Gate valve manufacturer. This Industrial High Pressure Gate Valve is a pipeline control equipment specially designed for harsh high pressure working conditions. It features a sturdy valve body and an optimized sealing structure, enabling reliable shut-off and long-term stable operation in high-pressure systems in industries such as petroleum, chemical engineering, and power stations.

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®️ is a leading China quality Double Offset Resilient Seated Butterfly Valve supplier. This Indusltrial Double Offset Resilient Seated Butterfly Valve adopts a double-biased design, which can reduce the excessive compression and wear of the sealing components, thereby extending the service life. The nickel alloy coating on the valve seat surface provides a lower friction coefficient during opening and closing. This High Performance Double Offset Resilient Seated Butterfly Valve offers an efficient solution for applications requiring long service life, low maintenance, and reliable sealing, and is particularly suitable for industries such as chemical, power, and water treatment.

LYV® is a leading China quality Reduced Bore Ball Valve supplier. This valve is a High Performance Reduced Bore Ball Valve specially designed for precise control of small flow rates. This Reduced Port Ball Valve achieves more precise regulation and shut-off of fluids through a unique structure where the diameter of the ball is smaller than that of the pipe. It combines the advantage of rapid opening and closing of ball valves with the control ability of needle valves, and is an indispensable key component in instruments and meters, experimental devices, and fine chemical processes.

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.
