Solenoid Operated Seat Valve series SWS22

Pressure [bar]


Flow rate [L/min]


Series SWS22… sandwich valves are high performance, 2/2 solenoid operated seat valves with a size 07 interface to ISO 4401-07-07. The main components of the valves are a sandwich body (stack-mounting body) and the screw-in cartridge (type WS22G / O…-16…). The 2/2 solenoid operated cartridge seat valve is designed on the poppet/seat principle, and is therefore virtually leak-free in both directions of flow (bidirectional seat-valve shut-off). These sandwich valves can be supplied as de-energized-closed or deenergized-open models, and as inline (in P) or bypass (in PT, AT, or BT) functions. These 2/2 solenoid operated seat valves are predominantly used in certain mobile and industrial applications where leak-tight shut-off functions are crucially important. Examples are where loads, tensions, or clamping forces must be held without leakage. All external parts of the cartridge are zinc-nickel plated according to DIN EN ISO 19 598 and are thus suitable for use in the harshest operating environments.
