The CGA 580 cylinder valve is a high-pressure valve designed for compressed inert gas cylinders, including nitrogen, argon and helium. The CGA-580 outlet connection is commonly used for compatible inert-gas regulators and equipment, helping prevent incorrect connections between different gas services.
Manufactured with a heavy-duty forged brass body and precision-machined internal components, this valve is designed for reliable operation in industrial gas cylinder applications. It is available with different inlet threads, pressure ratings, pressure relief devices (PRDs), sealing components and dip-tube configurations. See our gas cylinder valves for other cylinder valve configurations and connection options.

Key Features
- CGA-580 outlet: Standard outlet connection for compatible inert-gas regulators and equipment.
- Forged brass body: Durable construction for high-pressure cylinder applications.
- Precision-machined components: Controlled machining supports reliable valve operation and sealing.
- Pressure relief device: PRD configurations are available according to application requirements.
- Direct-drive stem design: Designed for low operating torque and smooth operation.
- Reliable sealing: O-ring sealing configurations and metal-to-metal sealing below the bonnet threads help provide leak-tight performance.
- Dip-tube option: Available when required by the cylinder application.
- Quality testing: Automated assembly, dimensional inspection, pressure verification and leak testing are used during production.
- Helium leak testing: 100% helium leak testing is available where specified for the valve configuration.
Applications
CGA 580 cylinder valves are commonly used with compressed inert gases in industrial and commercial applications, including:
- Nitrogen cylinders: Purging, blanketing, pressurization and industrial gas supply
- Argon cylinders: Welding, metal fabrication and shielding gas applications
- Helium cylinders: Leak detection, laboratory and specialized industrial applications
- Laboratory gas systems: Carrier gas and analytical equipment applications
- Food and beverage: Nitrogen pressurization and modified atmosphere applications
- HVAC and testing: Pressure testing and system purging
The valve configuration should be selected according to the gas service, cylinder specification, operating pressure, cleanliness requirements and applicable regulations.
Manufacturing and Quality Control
The CGA 580 cylinder valve is manufactured using controlled machining, assembly and inspection processes. Production quality control may include raw material inspection, precision machining, automated assembly, dimensional inspection, pressure integrity verification and leak testing.
Critical valve components are precisely machined to support consistent dimensions and reliable sealing. Depending on the specified configuration, 100% helium leak testing can be performed to verify sealing performance before shipment.
Installation and servicing of cylinder valves must be performed by qualified personnel in accordance with applicable cylinder and gas-service requirements.

Safety and Compliance
CGA 580 valves are intended for compatible compressed inert-gas cylinder applications. Valve selection must take into account the gas service, cylinder design, pressure rating, PRD requirements and applicable standards.
Compressed gas cylinders and valves contain stored energy and must be handled with appropriate safety procedures. Valve installation, removal and servicing should be carried out by a qualified cylinder technician.
