The 4WE 6 valves are directional piston valves, directly operated by high-performance solenoids. Compatible with DIN 24340 Form A and ISO 4401 bore configurations, these valves offer variable mounting options. They support DC or AC solenoids, with removable and 90° adjustable coils. Coil replacement does not require opening the pressure chamber. Electrical connections can be individual or central, with optional emergency actuation and soft-switching available. Inductive limit switch options are included.
