TYPICAL VALVES AND

ELECTRONICS

Valves adapted to the various applications ensure that the different requirements such as
small leakage, freely adjustable volume flows or pressures as well as seat tight closing of
control lines can be readily realised. The solenoid actuated valves can be used in zones 0
to 2 depending on the solenoid

POPPET VALVES AEXD, SVYP FEATURES
For tight closing functions such as leakage-free load holding,
clamping and gripping or for pilot control of larger valves.
CHARACTERISTICS
• Excellent durable tightness as a result of metallically
sealing seat
• Flange or cartridge construction
• 2/2- or 3/2-way execution
• Direct or pilot operated
• Detented execution
• Position monitoring with limit switch (Z104)
• Ex d or Ex i execution
• Low power execution with 6 watt solenoid

SPOOL VALVES WDZF, WDYF FEATURES
Control of the oil flow in two different directions.

CHARACTERISTICS
• Direct and pilot operated
• 4/2- and 4/3-way execution
• Detented execution
• Position monitoring with limit switch (Z104)
• Ex d or Ex i execution
• Pressure max. 350 bar
• Flow max. 160 l/min
• Nominal sizes NG4, NG6, NG10

SPOOL / POPPET VALVES WITH LIMIT SWITCH FEATURES
WDYF, AEXD Monitoring and display of valve switching position. The posi-
tion of the valve spool is detected with a proximity switch.
CHARACTERISTICS
• Inductive proximity switch

• Proximity switch Ex-protection certified
• Nominal size NG6
