Series R4R*P2 (In-line Mounted)
General Description
Series R4R*P2 proportional pressure reducing valves
are based on the mechanically adjusted Series R4R.
The additional proportional unit between the mechani-
cal pilot valve and the main stage allows continuous
pressure adjustment.
The optimum performance can be achieved in combi-
nation with the digital ampliļ¬er module PCD00A-400.
Features
ā¢
Pilot operated with proportional solenoid.
ā¢
Normally closed to avoid undesired motion.
ā¢
Continuous adjustment by proportional solenoid.
ā¢
2 interfaces:
ā L-body (R4R06-G3/4", R4R10-G1-1/4") BSPP
ā T-body (R4R03-G1/2", R4R06-G1") BSPP
ā¢
4 sizes (SAE 1/2", 3/4", 1", 1-1/4").
ā¢
3 pressure ranges.
ā¢
With mechanical maximum pressure adjustment.
