Features
|
- Load independent flow control corresponds to the
spool-position proportional to the electrical input
signal.
- The pump pressure always corresponds to the user
pressure, +3,6,8 or 12 bar (43, 86, 114 or 172 psi)
Dp compensator.
- The built-in pump-unloading valve results in:
- very low power turned into heat;
- minimum loading of the prime mover.
- User speed is precisely controlled under all load
conditions.
- Progressive regulating curve; no pressure peaks
when switching; sensitive control even for altern-ating
pressures.
- Constant working speed of differential cylinders at
the different regulating flow to the valve by grinding
angle.
- Constant recirculation pressure independent of the
number of units.
- Any limiting of flow for every user port.
- Load independent switching adjustment, constant
acceleration and deceleration.
- Proportional solenoids with longer life for the
armature in the oil (explosion proof solenoids "EEx
mII T4 or T5", available).
- Proportional directional control valves also
available as:
- Manual proportional series MHV
- Hydraulic proportional series MOV.
Any combination of these control options is
possible.
- The sub plate system allows a construction up to
8 control valves.
