ompensation valve type
UZUC6

UZUC6
… is intended for
keeping the constant flow rate of hydraulic fluid,
independently of the pressure at the receiver
(a cylinder) in systems, where the main working stream
(the flow) is controlled with throttling. The valve is
adjusted for inter-plate installation, dedicated for
hydraulic systems with proportional valves and
subplate connection acc. to ISO 4401
