Ultra-Clean Medical Gas Canister Valve for Oxygen Therapy and Calibration Gases with Diaphragm Seal
Product Description:
Engineered for purity and reliability in life-saving and sensitive applications, this Ultra-Clean Medical Gas Canister Valve is designed for medical oxygen and laboratory calibration gases. The valve is constructed from 316L stainless steel and features a proprietary diaphragm seal mechanism instead of a traditional stem packing. This design completely isolates the internal mechanism from the gas stream, eliminating a potential source of contamination and ensuring the highest gas purity. The outlet valve utilizes a specific medical thread (e.g., BS341, Pin-Index) to prevent misconnection—a critical safety feature. The entire valve assembly is cleaned, assembled, and packaged in a controlled environment to meet ISO 13485 standards. This gas valve is the trusted choice for hospitals, clinics, and analytical laboratories where gas integrity and patient safety are paramount.

FAQ:
-
-
Q: Why is a diaphragm seal important in a medical gas canister valve?
A: It prevents lubricants and potential contaminants from the stem assembly from entering the gas stream, which is critical for patient inhalation and sensitive analytical instruments.
-
Q: What certifications do you hold for medical-grade valve assembly production?
A: Our manufacturing facility is ISO 13485 certified, and we can provide valves with full material certifications and test reports to support your regulatory submissions.
-
Q: How does the outlet valve prevent misconnection between different medical gases?
A: It uses the Pin-Index Safety System (PISS) or other non-interchangeable thread standards, which physically prevent an oxygen regulator from connecting to a nitrous oxide cylinder, for example.
-
Q: Can this gas valve be used with all common medical gases?
A: Yes, its 316L stainless steel construction and diaphragm seal are compatible with oxygen, nitrous oxide, medical air, and helium.
-
Q: What is the cleaning standard for the internal passages of the cylinder valve?
A: We can provide valves cleaned to meet CGA G-4.1 for oxygen service and other specific purity levels, with documentation to prove compliance
