Series SPC
General Description
Series SPC sandwich type pressure compensators
are typically used in combination with proportional
directional control valves. The compensator keeps the
pressure drop over the directional valve constant and
thus provides load-independent ļ¬‚ow to the actuator.
Features
ā€¢
2-way or 3-way pressure compensators.
ā€¢
Standard pressure differential 5 Bar (73 PSI).
ā€¢
Adjustable differential (2 to 5 Bar) (29 to 73 PSI) and
10 Bar (145 PSI) optional.
