HUMPHREY GLUE VALVES
Humphrey glue valves are specially designed 2 way, air pilot valves with full .125″ or .250″ orifice. The double air pilot design provides a positive shut-off of the glue flow when the valve is De-energized. The no drip feature prevents unwanted glue deposit due to suck back created by the volume under the top diaphragm when the valve is closed, R561, R332, R332C.
