Cylinder Safety Lock Valve MHRB
Check-Q-Meter FD
Cylinder safety lock valve MHRB
U Used in mobile hydraulics, e.g.
excavators, excavator loaders,
cranes
U No lowering of the load in the
neutral position (additional
anti-drift valves are no longer
required)
U Direct flange connection to the
cylinder
U Very good, uniform precision
control characteristics in each
cylinder position
U Leak-free design
Check-Q-meter FD
Sizes 12...32
Versions
• Cartridge
• Subplate
U Controlled check valve
(leak-free)
U Outflow controlled in accordance
with the inflow on the
side opposite the actuator
U Free flow in the opposite
direction
U Used in hydraulic systems for
load-independent speed control
of hydraulic motors and
cylinders with pulling loads
U With/without secondary
pressure limitation
U Ratio of pilot pressure : load
pressure = 1 : 20
