China Reducing Ball Valves Manufacturer, Supplier, Factory

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.

As a type of Check valve, the 1500LB swing check valve uses the swing disk as the sealing structure. , and uses carbon steel as body material. LYV®️ 1500LB swing check valve can meet standards such as API, DIN.

LYV®️ Gas-over-oil actuated BW ends ball valve can meet standards such as API, DIN. Produce size range from NPS2 inch up to 24 inch, DN50 to DN600.

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.

LYV®️ large DN size oxygen ball valve is a special valve specially designed for oxygen pipe network, which is widely used in the pipe network of steel, metallurgy, petrochemical, chemical and other oxygen-using projects. In addition to the functions of ordinary valves, it also has its own characteristics such as good flame retardancy, good electrical conductivity, fast heat transfer, compact structure, oil resistance, safety and reliability. Strict oil prohibition measures are adopted during manufacturing, and all parts are subjected to strict degreasing treatment before installation. All diameter valves are equipped with conductive screw holes at the flange ends to prevent static electricity. The exposed parts of the valve have protective measures to prevent dust and oil pollution. With the valve seat of the metallurgical industry, the special oxygen ball valve and the special oxygen stop valve are widely used in steel, medicine, chemical and other industries.

The electric actuated plunger valve is a new multifunctional valve suitable for urban water supply, industrial water supply, mining water use, power plants, and water diversion projects in pipeline systems.
