Characteristics
The WLL directional control valve series of the nominal
size NG10 (CETOP 5) provides variable flow rates.
These valves are available with/without spool position
feedback and electrically controlled by the external dig-
ital amplifier modules VRD350/355 or PWD00A-400.
Typical applications are:
Exact and repeatible adjustment of flow rates, applica-
tions with rapid / slow speed profile and the positioning
of hydraulic drives.
Technical features
• Spool / sleeve design
• High reproducibility from valve to valve
• Low hysteresis
• Progressive flow characteristics for sensitive adjust-
ment of flow rate
• Manual override
• Spool position feedback, optional
