ABSTRACT:
A cartridge solenoid poppet valve (10) arranged to use a single size pilot valve (31) with any one of a set of a plurality of different size sets of valve seat members (14) and poppet valves (24). Pilot guides (175) are provided having different transverse extents to accommodate such different size valve members. The valve further includes a flatted pilot guide (32) defining flow passages communicated between a transfer chamber (35) and a pilot valve chamber (30) in which the pilot valve (31) is disposed. A T-slot (58) is provided in the solenoid plunger (38) extending fully diametrically thereacross and the pilot valve includes a T-shaped connecting head (71) received therein. The plunger (38) and plug (41) define cooperating stop surfaces (67,70) for maintaining a small spacing between the plunger and plug at all times.
