ABSTRACT:
An all ports in body, solenoid operated valve assembly includes a valve body and a valve operator mounted on the body with an electromagnetic core featuring a center leg projecting axially beyond the solenoid coil. A plunger and seal assembly is mounted for reciprocation along a path of movement aligned with the core center leg. The plunger and seal assembly is remotely located from the coil and all flow passages are formed in the assembly such that fluid flow through the center of the coil is excluded to minimize heat transfer to the confined fluid being controlled when the valve is electrically energized and to prolong the orifice seal life of the assembly.
