Gas Cylinder Valves
Industrial high-pressure gas cylinder valves for Oxygen, Air, Nitrogen, CO2 and special gas systems. Designed for safety, sealing performance, and long service life in demanding environments.
What is a Gas Cylinder Valve?
A gas cylinder valve is a critical pressure control component installed on gas storage cylinders. It controls gas release, ensures sealing safety, and regulates high-pressure flow in industrial and medical applications. These valves are widely used in oxygen supply systems, industrial gas distribution, welding operations, laboratories, and fire protection systems.
Our valves are engineered with precision machining technology to ensure stable pressure resistance, anti-leakage performance, and compatibility with international gas standards.
Precision Engineering for Industrial Gas Control
Our Gas Cylinder Valves are manufactured using high-strength brass and alloy materials, ensuring excellent corrosion resistance and long-term durability under high-pressure conditions.
Each valve undergoes strict leakage testing and pressure calibration to guarantee stable gas output. The design supports multiple international thread standards including PZ27.8, G5/8, W21.8, CGA320, and NPT systems.
This makes our valves fully compatible with global industrial gas cylinder systems used in Europe, North America, Oceania, and Asia markets.
Key Features
- High-pressure rating up to 15MPa industrial standard
- Compatible gases: Oxygen (O2), Air, Nitrogen (N2), Carbon Dioxide (CO2)
- Multiple thread standards for global compatibility
- Precision sealing structure ensures zero leakage performance
- Safety valve options up to 33MPa protection system
- Corrosion-resistant brass / alloy body construction
- Stable flow control for medical and industrial applications
Industrial Applications
Gas Cylinder Valves are widely used in oxygen therapy systems, industrial welding gas supply, chemical laboratories, steel manufacturing, shipbuilding industries, and fire protection systems.
Their stable performance ensures safe gas release control, preventing pressure failure, leakage risks, and operational hazards in high-demand industrial environments.
