The 4323C and 4333B Lecture Bottle Control Valves have been specifically designed for use with gases supplied in lecture bottles. This valve functions as a metering valve and is a rough control for dispensing gas products from lecture bottles. It does not control pressure or back-pressure from a source and/or delivery system.
If greater accuracy is required for the application, Matheson recommends the use of the appropriate lecture bottle regulator listed in the Regulator Section of this catalog. The Lecture Bottle Control Valves should be used with gases compatible with the materials of construction listed under the Specifications.
