CGA 540 Oxygen Cylinder Valve
The CGA 540 oxygen cylinder valve is a precision-engineered component used to safely regulate the flow of oxygen gas from high-pressure cylinders.
Commonly employed in medical, industrial, and welding applications, these valves are designed to maintain performance under challenging conditions.
DSW manufactures CGA 540 valves that comply with international quality standards, ensuring reliability, safety, and ease of use.
Select a valve with the same CGA as your oxygen gas cylinder or other system components.
The valves have gauges to monitor the outlet pressure, as well as indicators to monitor the inlet pressure.

Valve Construction & Components
The CGA 540 valve is composed of several critical components:
- Body: Made from brass or stainless steel, houses the internal mechanisms.
- Handwheel: Controls the opening and closing of the valve.
- Stem: Connects the handwheel to the internal sealing mechanisms.
- Yoke: Secures the valve to the gas cylinder.
- Diaphragm: Flexible component that helps regulate gas flow.
- Seat: Provides a sealing surface to stop gas flow when closed.
Understanding these parts helps users perform regular maintenance and identify wear for timely replacements.

Applications
Medical Oxygen Therapy CGA 540 valves play a vital role in delivering oxygen therapy. The valve ensures safe, accurate regulation of oxygen from the cylinder to the patient. Healthcare professionals rely on these valves to maintain consistent oxygen flow, which is critical for patient health.
Industrial and Welding Use In cutting, welding, and brazing operations, these valves regulate oxygen supply with dependable performance under high pressure. Their robust construction and pressure-stable design make them suitable for heavy-duty industrial environments.
Frequently asked questions about the CGA 540 valve
Q: What is the CGA 540 valve used for?
A: The valve regulates oxygen flow from a cylinder to a patient in medical oxygen therapy.
Q: Is the CGA 540 valve compatible with all oxygen cylinders?
A: The valve is designed to fit only specific oxygen cylinders with a compatible thread.
Q: How do I know if my CGA 540 valve works appropriately?
A: You can test the valve by attaching it to an oxygen cylinder and opening it. The flow rate should be steady, and the valve should not leak.
Q: How often should I inspect and clean my CGA 540 valve?
A: The valve should be inspected and cleaned regularly, at least once monthly, to ensure proper operation and prevent problems.
