China Pneumatic Ball Valve Manufacturer, Supplier, Factory

LYV® is a China quality aluminum bronze gate valve supplier. This Aluminum Bronze Marine Gate Valve is specially designed for corrosive and special safety requirements working conditions. This valve is cast from aluminum bronze alloy and features excellent resistance to seawater corrosion, wear and explosion-proof properties. Our API 600 Aluminum Bronze Gate Valve is suitable for harsh environments such as ships, offshore platforms and chemical plants where corrosive media exist or sparks need to be avoided.

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 professional China DBB Inject Ball Valve manufacturer. This is a special type of ball valve that integrates the dual-blocking and venting (DBB) functions. It is specifically designed for critical operating conditions where dual isolation, intermediate chamber pressure relief, and fluid injection need to be achieved within a single volume. This DBB Injection Ball Valve is a key equipment used in the process industries such as oil, gas, and chemicals for safety maintenance, instrument calibration, and chemical agent addition.

LYV® is a China quality swing check valve supplier. This Industrial Swing Check Valve is a type of valve that automatically opens and closes based on the flow of the medium itself. Its main function is to prevent the backflow of the medium in the pipeline, thereby protecting the upstream equipment and ensuring the safety of the system.This API 6D Swing Check Valve features flexible opening and closing, reliable sealing, and easy maintenance as a high performance pipe safety equipment.
