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®️ 1500LB Globe valve can meet standards such as API, DIN, ISO, GOST, GB, JIS. Produce size range from NPS10 inch up to 10 inch , DN250 to DN250. Pressure rating covers ANSI Class1500LB and PN250.

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®️ 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 slow acting check valve also called as slow closing valve, is designed for water supply, air conditioning, and fire protection piping systems, suitable for water as the medium with a temperature up to 80°C.
