Abstract
An electromagnetically actuated, pilot operated valve having a nonmetallic body with a pressure responsive diaphragm for opening the main valve and defining, in cooperation with a guide member, a pilot chamber having an armature/pilot valve member movably received thereon. The guide member has a bleed-supply hole formed therein and is secured to the body by an annular member attached to the body by nonmetallic weldment and integrally defining a cup into which a solenoid coil is received over the guide member and potted by liquid-cast insulating material. An armature guide member-diaphragm subassembly has the guide with armature received therein with the diaphragm peripherally secured thereto by a ring pressed thereover, the ring interfitting with cooperating body surfaces to define restricted passage to filter flow to the pilot chamber bleed hole.
