Abstract

diaphragm valve (20) comprising a solenoid body (26) having a coil (54) and a pole piece (56) positioned in the solenoid body (26) and a valve body cartridge (24) connected to the solenoid body (26). An armature (62) is slidably disposed in the solenoid body (26) for movement along a longitudinal axis between an energized position and a de-energized position. A valve member (114) is slidably disposed in the valve body cartridge (24) and is connected to the armature (62) for movement therewith. A biasing member (102) is disposed in the solenoid body (26) that acts to normally bias the armature (62) toward the de-energized position. A diaphragm (120) extends inwardly from the valve body cartridge (24) and between the armature (62) and the valve member (114), such that the diaphragm (120) deflects in response to movement of the armature (62) and the valve member (114) along the longitudinal axis. A diaphragm support sleeve (144) has a support sleeve wall (146) defining a sleeve cavity (150) that receives at least part of the armature (62), and a support sleeve flange (148) that extends inwardly and is transverse to the support sleeve wall (146). The support sleeve flange (148) abuts and supports at least part of the diaphragm (120), which is clamped between the valve body cartridge (24) and the diaphragm support sleeve (144). The diaphragm (120) prevents contaminants from working their way toward the solenoid body (26) whilst permitting longitudinal movement of the valve member (114).
