Medical Gas Ball Valves for Healthcare and Oxygen Service
Medical gas ball valves are valves specially designed and prepared for use with medical gases including oxygen, nitrogen, medical air, air, and vacuum within the medical support infrastructure of hospitals and, surgery centers, and medical facilities. These medical valves are manufactured and tested in facilities with a high cleanliness level compared to standard ball valves to ensure no contamination in critical life-support medical applications.
The design is specialized to allow for ease of installation and service, with extended tube ends and a 3-piece field serviceable design. Reliable medical gas ball valves are a critical component of medical gas piping systems, ensuring zone isolation, serviceability, and compliance with established national standards.
Our Medical Gas Ball Valves conform to NFPA 99–2018, section 5.1.4.3. Valves are full port, 1/4 turn, double seal, ball-type, three piece design with forged brass body and chrome-plated brass ball. They are assembled with PTFE ball seats and stem seals and support working pressures up to 600 psig. Seats, seals, lubricants and valve materials are compatible with USP oxygen, nitrous oxide, medical air, carbon dioxide, helium, nitrogen and mixtures at continuous pressure of up to 600 psig and vacuum service to 29" Hg.
CGA G-4.1Oxygen Cleaning is standard for all medical gas ball valves supplied to medical facilities. After cleaning, valves are capped and sealed in polyethylene packaging to maintain purity. Medical Gas Ball Valves are assembled with Type-K copper tube extensions and dual gage ports for easy installation into medical gas pipelines.

Frequently Asked Questions About Medical Gas Ball Valves
What is a ball valve for medical gas?
US Valve medical gas ball valves are a full port, quarter-turn shutoff valves manufactured and cleaned specifically for use in hospital and medical facilityl gas piping systems. Unlike standard ball valves, these are oxygen cleaned per CGA G-4.1, constructed from forged brass, and conform to NFPA 99-2018, section 5.1.4.3, to ensure patient safety and national code compliance.
Can any ball valve be used for medical gas?
No. Standard ball valves cannot be used in medical gas piping systems. Medical gas ball valves must be manufactured and cleaned specifically for oxygen service per CGA G-4.1, comply with NFPA 99-2018 section 5.1.4.3, and use materials compatible with USP oxygen, nitrous oxide, medical air, and other medical gases at pressures up to 600 psig working pressure.
Which valves are used in a medical gas piping system?
Medical gas piping systems typically require several valve types, including ball valves for zone isolation and main shutoffs, check valves to prevent backflow, and relief valves for pressure protection. All must conform to NFPA 99-2018 and be cleaned for oxygen service. U.S. Valve manufactures medical gas ball valves and medical gas check valves for these applications.
What does NFPA 99-2018 require for medical gas shutoff valves?
Per NFPA 99-2018, section 5.1.4.3, medical gas shutoff valves must be full port, ball-type, 1/4-turn, double seal, and three-piece in design, with a forged brass body. They must also be cleaned for oxygen service in accordance with CGA G-4.1 and be rated for working pressures up to 600 psig working pressure.
