Series R4V*P2 (In-line Mounted)
General Description
Series R4V*P2 proportional pressure relief valves are
based on the mechanically adjusted Series R4V. The
additional proportional unit between the mechanical
pilot valve and the main stage allows continuous
pressure adjustment.
The optimum performance can be achieved in
combination with the digital ampliļ¬er module
PCD00A-400.
