Cylinder flow valve.
Accession #: 2008173
Description: A non-standard cylinder connection and needle valve. Chromium plated suggesting intended for domestic or medical use.The absence of a pressure regulator makes the flow dependent on cylinder pressure and the absence of a pressure dial makes it impossible to predict imminent cylinder emptying. The outlet nozzle is for a rubber tube which would blow off if the outlet pressure were to rise significantly. Primitive and inadequate for clinical purposes
