MEDICAL GAS CHECK VALVES

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.

We control the material of PTFE and stainless steel wires per customer's request.

• Some are from Japan and Taiwan, some are from China local. Only choose high quality material.
  We test leakage of each roll before braiding, then we cut 300mm and crimp it to test

• burst pressure after brading.
  We use CNC Lathes Machine for end fittings production. Machine system, knife and inspection

• tools are all imported from Japan.
  We use Techmaflex Crimping Machine which is imported from France. This machine has

• accurate and stable performance for crimping because it is produced for PTFE hose crimping only.
