Introduction

Product Introduction

LYV® Large DN Size Oxygen Ball Valve is a safety-specific valve developed for the characteristics of oxygen medium. The core of its design lies in meeting the strict safety requirements for oxygen applications:

●All components undergo strict degreasing treatment before production and assembly, completely eliminating the risk of oil contamination

●The flange end is equipped with dedicated conductive screw holes to effectively discharge static electricity

●The Ball Valve for Oxygen Services as a whole is made of materials with flame-retardant and conductive properties. Combined with a compact structural design and a dedicated valve seat, it ensures long-term safe and reliable operation in high-purity, high-pressure oxygen environments

Therefore, this Industrial Large DN Size Oxygen Ball Valve has become a key equipment choice for safe transportation in large and medium-sized oxygen pipeline networks in fields such as steel and metallurgy, petrochemicals, medicine, and chemical engineering.

Features

■ The design and manufacture of the oxygen ball valve meet the relevant requirements of GB16912.

■ Strict oil prohibition measures are adopted during manufacturing.

■ All parts are subjected to strict degreasing treatment before installation.

■ The exposed part of the valve stem should have protective measures to prevent contamination by dust and oil, and be marked with a "no oil" mark.

■ The flow channel surface of the inner cavity should be smooth and smooth.

■ The valve should be designed with obvious opening indication, and the handwheel should have the word "on-off" and an arrow on it.

■ Conductive screw holes should be provided on the end flange of the valve to make the bolt connection wire well grounded to prevent static electricity.

■ The lubrication of the support bearing should use fluorinated grease lubricant.

■ For valves with a nominal size of DN>150, the manufacturer recommends that a bypass device should be installed in the structure, and there should be an obvious flow direction mark.

What's the main applications of LYV®️ large DN size oxygen ball valve?

This valve is specially designed for harsh environments dealing with high-purity and high-pressure oxygen. Its oil-free, anti-static and flame-retardant features are mandatory requirements for ensuring system safety, rather than optional functions of ordinary valves. In the steel and chemical industries, it is often used in key positions such as the outlet pipes of oxygen production stations, oxygen gun valve stations, and the entrances of various oxygen-consuming workshops. It is one of the core components in the oxygen delivery system to prevent explosion and combustion accidents.

Why choose LYV®️ large DN size oxygen ball valve?

LYV®️ has been producing large DN size oxygen ball valve for over 16 years. The workshop covers 13000 square meters and own more than 50 advanced CNC machines. Our engineers & production team will make sure your order delivers with high-quality and fastest time. We also care about valve shipping. The valves will wrap by bubble pouches or paper to ensure the paint will not be damaged. We also fixed valve by plywood stick after we put valve into the box. The plywood case will be painted with necessary marking to make sure the valve will not be damaged during shipping.
