🔧 Oxygen Regulator – General Description
 
An oxygen regulator is a pressure-regulating device designed to safely control the flow and pressure of oxygen gas from a high-pressure cylinder to a usable level. It ensures a consistent and safe delivery of oxygen for various applications including:
Medical use (e.g., hospitals, home oxygen therapy)
Industrial welding/cutting
Aviation and diving systems
Laboratories and research
 
 
Feature
Description
Inlet Pressure
2000–3000 psi (138–207 bar), depending on cylinder
Outlet Pressure
Adjustable: typically 0–100 psi (industrial); 0–25 LPM (medical)
Flow Rate
Medical: 0–15 LPM (some go up to 25 LPM) Industrial: variable in SCFH
Inlet Connection
CGA 540 (industrial) / CGA 870 (medical post valve)
Outlet Connection
¼” NPT, DISS, or barb fitting (for tubing)
Material
Brass or chrome-plated brass (oxygen-compatible materials)
Gauge Type
Dual gauge: One for cylinder pressure, one for output pressure or flow
Flow Control
Knob or dial with fixed increments (LPM or psi)
Safety Features
Pressure relief valve, sintered filter, and check valves
Standards
Complies with ISO, ASTM, FDA, or NFPA (depending on application)
 
 
🔄 Types of Oxygen Regulators
 
Single-Stage Regulator
Reduces pressure in one step
Simpler and more compact
Two-Stage Regulator
More precise pressure control
Reduces pressure in two stages for consistent output
Medical Oxygen Regulator
Flowmeter built-in (LPM-based)
Compact, often used in home therapy
Industrial Oxygen Regulator
Heavier duty
Used in cutting, welding, etc.
