ABSTRACT:
A chemically inert diaphragm valve is provided in which the diaphragm is attached to the plunger of a solenoid by a threaded insert. The diaphragm material, which is preferably a relatively flexible, chemically inert material such as Kalrez or Chem-Raz, is molded around one end of a machined piece with the other end of the piece being threaded. The threaded end may be received by the tapped end of a solenoid plunger. The piece contained within the diaphragm material acts to stabilize cold-flow at the valve site as well as perform the valving function.
