SPECIAL VALVES

Wandfluh valves are constructed in a modular way and are thus very flexible in their
composition. This allows different standard functional elements to be combined, so that
individual solutions can be easily realised.

POPPET VALVES WITH DETENT FUNCTION CHARACTERISTICS
AEXD3206RR The practically leakage-free poppet valve spool can be opened
or closed against the applied spring pressure and mechani-
cally detented in the desired position by an electrical impulse.

FEATURES
• 3-way function
• Electrical actuation with standard or Ex d solenoids
• Combination of an electrical actuation with a mechanical
actuation possible
• Spool position monitored with position sensor
• Pressure max. 350 bar
A • Flow max. 40 l/min

VALVES WITH SWITCHING POSITION MONITORING CHARACTERISTICS
WDMFA_Z Electronic sensors detect the switching position of the valve
spool. The evaluation of the command/feedback signals con-
siderably increases the safety of an installation.
FEATURES
• For various spool and poppet valves
• In combination with standard and Ex d solenoids
• Inductive switching sensor
• Pressure max. 350 bar
• Flow max. 160 l/min

SEAT TIGHT PRESSURE CONTROLLERS MSDPM22 CHARACTERISTICS
Controls the set output pressure independently of the volume

flow and closes seat tight. This leads to a significant reduction
of losses in a hydraulic system.
FEATURES
• Manual adjustment of the output pressure
• Good pressure control in case of volume fl ow fl uctuations
• Seat tight
• Pressure max. 350 bar
• Flow max. 20 l/min
• Cartridge with cavity M22x1,5
