Specifications:
- Outlet Connection: Configured with a CGA 580 fitting, compliant with industry standards for inert gases.
- Inlet Connection: Equipped with a 3/4″ NGT (National Gas Taper) thread, ensuring secure and precise attachment to compatible gas cylinders.
- Maximum Operating Pressure: Rated for up to 3360 psi (21 MPa), designed for safe and reliable performance under high-pressure conditions.
Features:
Pressure Relief Device (PRD): Pressure relief device
Automated Assembly and Testing: Ensures high quality.
Helium Leak Tested: Ensures gas containment. 100% helium leak tested
Heavy-Duty Construction: Heavy-duty forged brass body for durability and high-pressure
Precisely machined internal components meet the most stringent international valve performance standards
Pressure Relief Device (PRD) is a unitized plug design that provides excellent flow characteristics and ensures proper assembly and tamper resistance
Metal-to-Metal Seal: Metal-to-metal seal below bonnet threads prevents pressure in the threads at the top of the valve body
Direct-drive stem design with optimized O-ring (GV) or double O-ring (GVHM) seal reduces friction and operates at deficient torque levels
Tapped for the dip tube as required
Common Applications:
The CGA580 valve is widely used across various sectors due to its reliability and compatibility with inert gases.
- Welding: Frequently employed in welding applications to ensure a secure and consistent gas supply.
- Industrial Processes: Used in numerous industrial operations that require inert gases.
- Specialised Gas Applications: Commonly applied for high-purity or specialty gases, including:
- High-purity argon, nitrogen, and oxygen
- Certain laboratory gases
- Industrial gases requiring specific fittings
The exact application of a CGA580 valve will depend on the type of gas and the regulator in use.
Safety Notice: CGA580 valves must be installed by a qualified cylinder technician. Compressed gas cylinders and valves are hazardous. Always observe proper safety precautions.
