FREQUENTLY ASKED QUESTIONS
What are oxygen cylinder valves used for?
Oxygen cylinder valves control the release of oxygen gas from a cylinder and connect it to regulators or delivery equipment.
They serve as the primary interface between the pressurized oxygen inside the cylinder and downstream systems. Proper valve operation ensures safe and consistent oxygen flow.
These valves are designed specifically for oxygen service.
Are oxygen valves gas-specific?
Yes, oxygen valves are gas-specific and must only be used for oxygen service.
Oxygen requires dedicated CGA valve standards to prevent incorrect connections and reduce fire risk. Using valves designed for other gases is unsafe and non-compliant.
Gas-specific valve design is a core requirement for industry safety.
What CGA valve types are used for oxygen?
Oxygen cylinders commonly use CGA-540 or CGA-870 valves.
CGA-540 valves are typically used for industrial oxygen applications, while CGA-870 post valves are standard in medical and dental settings. Selection depends on the cylinder and intended use.
Matching the correct CGA valve ensures regulator compatibility and safe operation.
Can an oxygen valve be replaced?
Yes, oxygen valves can be replaced if they are damaged, leaking, or out of specification.
Valve replacement must be performed by qualified personnel using approved procedures. Improper installation can compromise safety and oxygen delivery.
Replacement valves must meet CGA and DOT requirements for oxygen service.
Are oxygen valves compatible with all oxygen cylinders?
Oxygen valves are compatible only with cylinders designed and labeled for oxygen service.
Thread type, pressure rating, and outlet configuration must match the cylinder specification. Compatibility is essential for safe and compliant operation.
Cylinder markings should always be verified before valve installation.
Do oxygen valves require special cleanliness standards?
Yes, oxygen valves must meet strict cleanliness requirements.
Oxygen supports combustion, and contaminants such as oil or grease pose serious safety hazards. Oxygen valves are cleaned and prepared for oxygen service to minimize risk.
Cleanliness is critical in both industrial and medical oxygen systems.
What pressure ratings do oxygen valves support?
Oxygen valves are rated to meet or exceed the service pressure of oxygen cylinders.
Most oxygen cylinders operate at 2,000-2,200 PSI. Valves must be designed to contain these pressures safely.
Pressure ratings are defined by valve design and manufacturer specifications.
Are oxygen valves reusable?
Oxygen valves may be reused only if they remain within specification and pass inspection.
Valves exhibiting wear, contamination, or leakage should be replaced. Reuse decisions are commonly made during cylinder maintenance or recertification.
Safety considerations always take priority over reuse.
How do I choose the correct oxygen valve?
Choosing the correct oxygen valve depends on cylinder type, CGA standard, pressure rating, and regulator compatibility.
The valve must be rated explicitly for oxygen service and match the intended application. Incorrect selection can lead to unsafe connections or filling refusal.
When uncertain, customers should consult their gas supplier or equipment manufacturer.
Who should buy oxygen valves from Gas Cylinder Source?
Oxygen valves from Gas Cylinder Source are intended for use in welding shops, medical facilities, laboratories, manufacturers, and industrial service companies.
They are suitable for organizations that maintain oxygen cylinder fleets or refurbish equipment to ensure compliance.
Gas Cylinder Source supports both single-valve purchases and larger quantity orders for professional operations.
