Medical Gas Check Valves
Our Medical Non-Return Valves conform fully to NFPA 99–2018. The valve port is larger than the copper tube flow area to keep pressure drops low. Valves are designed for working pressures of up to 300 psig and the body is field removable for servicing without cutting or disassembling of lines. Valves are provided with type-K copper tube extensions for connections on the pipeline. All valves are supplied clean and prepared for oxygen service per CGA G-4.1. Valves are capped and packaged in a polyethylene bag to keep them clean.
