The M-SED 6 is a solenoid-operated, directly operated seat directional valve, compatible with DIN 24 340 Form A and ISO 4401/CETOP-RP121H bore configurations. It offers leak-free sealing, safe switching after long periods under pressure, oil-bath DC solenoids, and removable coils. The coil rotates every 90°, eliminating the need to open the pressure chamber for replacement. Individual electrical connection, emergency manual operation, and inductive position sensor are available as options.
