2-Port Pressure Compensator
Series R5A
R5A UK.INDD CM 02.08.11
Characteristics / Ordering Code
A (B1)
X1
Direct operated 2 way pressure compensators series
R5A can be combined with any type of fixed or adjust-
able flow resistor (throttle) to provide a load compensated
flow. The combination with the proportional throttle valve
F5C serves as a compact 2 way flow control unit in SAE
flange design. The R5A is typically used as meter-out
compensator behind the flow resistor.
Features
• Seated type 2 way pressure compensator
• SAE61 flange
• 8.4 bar control pressure
• 3 sizes, SAE 3/4“, 1“, 1 1/4“
• Load compensated flow in combination with F5C
Pilot connection on
inlet flange to link
with F5C valve.
