All breathing air valves offered by Gas Cylinder Source are manufactured to applicable CGA and industry standards and intended for installation on DOT-certified breathing air cylinders. These valves are designed for high-pressure service, typically 3,000 PSI or 4,500 PSI, and feature gas-specific outlet configurations that prevent cross-connection with industrial or non-respiratory gases.
Breathing air valves are a critical component in any respiratory air system. Proper valve selection ensures safe gas delivery, regulator compatibility, and compliance with OSHA, NFPA, CGA, and applicable fire or diving standards. Gas Cylinder Source supports professionals who replace worn valves, configure new cylinders, or maintain compliant breathing air systems.
All breathing air valves are intended for professional installation, inspection, and service. Because breathing air is used for human respiration, valve condition, cleanliness, and correct specification are essential for safe operation.
Don’t take chances with your breathing air valves. Insist on Sherwood quality for your critical oxygen uses. Sherwood valves deliver precise regulation, unmatched durability, and reliable performance, use after use.
FREQUENTLY ASKED QUESTIONS
What are breathing air valves used for?
Breathing air valves control the flow of compressed breathing air from a cylinder to respiratory equipment.
They serve as the primary connection point between the cylinder and regulators used in SCBA, SCUBA, and industrial breathing systems. Proper valve function is essential for reliable air delivery.
These valves are specifically designed for life-support air service.
Are breathing air valves different from industrial air valves?
Yes, breathing air valves are specifically designed for respiratory air service and are not interchangeable with industrial air valves.
They meet stricter standards for cleanliness, materials, and outlet configuration to prevent contamination and incorrect connections. Industrial air valves do not meet these requirements.
Using the correct breathing air valve is a fundamental safety requirement.
What pressure ratings do breathing air valves support?
Breathing air valves are commonly rated for 3,000 PSI or 4,500 PSI service.
The pressure rating must match the cylinder specification and intended use. High-pressure applications such as SCBA often require 4,500 PSI-rated valves.
Pressure ratings are defined by the valve design and stamped or documented by the manufacturer.
Are breathing air valves gas-specific?
Yes, breathing air valves are gas-specific and designed only for compressed breathing air.
Their outlet configurations prevent accidental connection to non-respiratory gases or incompatible regulators. This reduces the risk of serious injury or equipment failure.
Gas-specific design is mandated by industry standards.
Can a breathing air valve be replaced?
Yes, breathing air valves can be replaced when damaged, leaking, or out of specification.
Replacement must be performed by qualified technicians using approved procedures. Improper valve replacement can compromise cylinder safety and air quality.
Replacement valves must meet the same specifications as the original valve.
Are these valves compatible with SCBA and SCUBA equipment?
Breathing air valves are compatible with SCBA or SCUBA equipment when properly matched to the regulator system.
Different applications use different outlet standards and connection types. Compatibility depends on valve specification and equipment design.
Customers should confirm equipment requirements before purchasing a valve.
What materials are breathing air valves made from?
Breathing air valves are typically made from brass or specialized alloys suitable for high-pressure respiratory air service.
Materials are selected to resist corrosion, maintain structural integrity, and support clean air delivery. Material selection is governed by safety and industry standards.
Valve materials are not interchangeable across all gas types.
Are breathing air valves reusable?
Breathing air valves may be reused only if they pass inspection and remain within specification.
Valves exhibiting wear, contamination, or damage must be replaced. Reuse decisions are often made during cylinder inspection or recertification.
Safety and compliance take precedence over reuse.
How do I choose the correct breathing air valve?
Choosing the correct breathing air valve depends on cylinder pressure rating, outlet standard, and intended application.
The valve must match the cylinder specification and regulator system exactly. Incorrect selection can result in unsafe operation or equipment incompatibility.
When in doubt, customers should consult their equipment manufacturer or service provider.
Who should buy breathing air valves from Gas Cylinder Source?
Breathing air valves from Gas Cylinder Source are intended for fire departments, industrial safety teams, dive operations, and professional service providers.
They are suitable for organizations maintaining breathing air cylinder fleets or refurbishing equipment to ensure compliance.
Gas Cylinder Source supports both single-valve purchases and larger orders for professional operations.
