Cartridge Seat Valve series WS22G / O

Pressure [bar]


Flow rate [L/min]


These direct acting 2/2 solenoid operated directional seat valves, series WS22G…/WS22O…, are size 5, pressure balanced screw-in cartridges with a 3/4-16-UNF 2A or M20x1.5 mounting thread. They are designed on the poppet/seat principle, and are therefore virtually leak-free in both directions of flow (bidirectional seat-valve shut-off). “De-energised closed” and “de-energised open” functions are available. The straightforward design delivers an outstanding price/performance ratio. These 2/2 solenoid operated seat valves are primarily used as pilot valves 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
