RJV is assigned for turning on or turning off of a hydraulic engine, or that an engine after turning off remained in the same
level.According to a graphic mark RJV is directed fromAtowards B free flow. By flowing from B to A, a head body as well as
a control walve are by a spring pushed to a yoke(corbel). The flowing is closed.
The operating pressure is acting on a piston, elevate a control valve and than also a head body. The direction from B towards A
is opened.
RJVis usedin opened circuits or closed circuits.
