Oxygen Shut-Off Valve

Stainless steel oxygen valve is a special valve designed for oxygen pipeline networks. The main body is made of stainless steel or copper alloy material (such as SUS304, CF8), which has flame retardancy, high corrosion resistance, and excellent mechanical strength, and can safely control highly active gases such as oxygen. Its design follows explosion-proof safety standards, uses oil free degreasing technology to eliminate static electricity and grease risks, and is equipped with anti-static devices, fully enclosed brackets and other structures to prevent medium explosion. This valve combines low flow resistance and reliable sealing (body sealing or welding D802 sealing surface), suitable for rapid opening and closing and flow regulation of high-pressure oxygen pipelines in steel, metallurgy, chemical and other industries.

Optimization of fluid control efficiency

Optimization of fluid control efficiency
01
The surface of the inner cavity is polished to reduce oxygen flow resistance, decrease turbulence and pressure drop, and improve transportation efficiency. Special designs such as branch valves can accurately adjust oxygen distribution, adapting to the needs of multiple scenarios such as steel smelting and chemical industry.

Compact structure and convenient operation

Compact structure and convenient operation
01
Adopting modular design, it is compact in size but has high pressure bearing capacity, making it easy to install in narrow spaces. Some valves (such as ball valves) can be quickly opened and closed by rotating 90 °, supporting remote control and improving operational efficiency.

Strict sealing and surface treatment

Strict sealing and surface treatment
01
The sealing structure adopts corrosion-resistant materials such as polytetrafluoroethylene, and ensures zero leakage through precision machining to meet the stringent sealing requirements of oxygen systems. All components that come into contact with oxygen have undergone degreasing treatment to prevent oxidation reactions caused by oil stains, in compliance with the oil prohibition standards for oxygen specific valves.

Anti ignition and flame retardant design

Anti ignition and flame retardant design
01
The key components are made of copper alloy or stainless steel with excellent flame retardancy, which will not produce sparks even when rubbed against solid particles in high-speed oxygen flow, fundamentally eliminating the risk of explosion. Some designs also incorporate dust-proof and waterproof devices to further reduce safety hazards.

Excellent material properties

Excellent material properties
01
Made of stainless steel materials (such as 304, 316L, etc.), it has excellent corrosion resistance and can effectively resist the high oxidative corrosion of oxygen media, extending its service life. At the same time, stainless steel has both high strength and toughness, and can withstand high pressure (such as the common high-pressure oxygen delivery in oxygen plants) and temperature fluctuations, ensuring the structural integrity of valves under extreme working conditions.
