MANIFOLD VALVE SYSTEM FOR FIBER LASER CNC MACHINES

About MANIFOLD VALVE SYSTEM FOR FIBER LASER CNC MACHINES

SMC & CNC Laser Gas Manifold System Specification

1. General Description

Laser gas manifold systems are designed to deliver high-purity assist gases (typically O, N or CO to CNC laser machines. The manifold system controls pressure, flow rate, and gas switching while ensuring safety and minimizing contamination.

2. Key Components

ComponentDescription

Inlet ConnectionsCompatible with high-pressure gas cylinders (typically 200- 300 bar)

Pressure RegulatorsDual-stage or single-stage, depending on application; maintains consistent outlet pressure

Gas FiltersRemoves particulates and ensures gas purity

Solenoid ValvesFor remote or automatic gas switching

Pressure GaugesInlet and outlet pressure indication (usually analog or digital)

Outlet ConnectionsConfigurable to suit CNC machine input (e.g., or custom fittings)

Safety Relief ValvePrevents overpressure scenarios

Piping MaterialStainless steel (SS316/SS304) or brass (nickel-plated), depending on gas type and purity requirement

Mounting OptionsWall-mount or rack-mount options available

Purge ValvesFor inert gas purging to prevent contamination

3. Gas Compatibility

Oxygen (O): Medical- or industrial-grade; use O-compatible components (no lubricants that can combust)

Nitrogen (N): Inert; used for high-speed cutting, especially for stainless steel

Carbon Dioxide (CO): For specific laser applications; piping must be CO-compatible

4. Operating Parameters

ParameterValue

Inlet Pressure150- 300 bar (max 350 bar for some designs)

Outlet Pressure0.5- 30 bar adjustable (depending on regulator design)

Flow RateUp to 100 Nm/hr (varies by configuration)

Temperature Range-20C to +60C typical

Leak Rate 1x1 mbar l/s (He leak test standard)

5. Control Options

Manual Operation: Via hand-operated valves and regulators

Pneumatic/Electronic: Via PLC or CNC signal integration
