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. Perfect coordination of valve and
electronics leads to simple drive solutions for precise movements and sensitive valve
actuation.

SPOOL VALVES, FLANGE WDMF CHARACTERISTICS
Controls the oil flow and can thus, for example, determine the

direction of movement of a cylinder. The valve is screwed as a
flange onto a standardised mounting interface.

FEATURES
• Solenoid valve remotely controlled via intelligent electronics
• Direct or pilot operated
• Optionally detented, for safety in the case of power failure
• Small losses due to low leakage
• Soft switching for reduction of shocks
• Switching position monitoring
AB1 • Pressure max. 350 bar

SPOOL VALVES FLANGE WDPFA CHARACTERISTICS

The volume flow is controlled proportionally to the solenoid
current. A cylinder can thus be moved forward and backward
at variable speed.
FEATURES
• Progressive characteristic
• Good repeatability
• Direct or pilot operated
• Pressure max. 350 bar
• Flow max. 200 l/min
• Nominal sizes NG3, NG4, NG6, NG10

PRESSURE REDUCING VALVES MDPP, MVPP CHARACTERISTICS
Reduces the input pressure to the desired output pressure.
The pressure in A is continuously adjusted via the solenoid
current.

FEATURES
• Linear characteristics and precise reproducibility
• Direct or pilot operated
• Pressure max. 350 bar
• Flow max. 250 l/min
