A proportional valve (100) is provided that includes a movable armature (104) within a body (102), with the armature (104) including a poppet (107) and with the body (102) including one or more inflow ports (135) and an outflow bore (123), a valve seat (120) located on a projecting valve seat structure (119), with the valve seat (120) including a valve orifice (130) in fluid communication with the one or more inflow ports (135) and the outflow bore (123), and a flow flange (116) extending from the poppet (107) and including a flow flange wall (117) that surrounds the valve seat (120), forming a flange inflow channel (129) of a predetermined cross-sectional inflow area between the flow flange wall (117) and the valve seat structure (119), wherein the poppet (107) moves between closed and opened positions without changing the predetermined cross-sectional inflow area provided by the inflow channel (129). |

1. A proportional valve (100), comprising:
a movable armature (104) within a body (102), with the armature (104) including a poppet (107) and with the body (102) including one or more inflow ports (135) and an outflow bore (123); a valve seat (120) located on a projecting valve seat structure (119), with the valve seat (120) including a valve orifice (130) in fluid communication with the one or more inflow ports (135) and the outflow bore (123); and a flow flange (116) extending from the poppet (107) and including a flow flange wall (117) that surrounds the valve seat (120), forming a flange inflow channel (129) of a predetermined cross-sectional inflow area between the flow flange wall (117) and the valve seat structure (119), wherein the poppet (107) moves between substantially fully closed and substantially fully opened positions without changing the predetermined cross-sectional inflow area provided by the inflow channel (129). |
