RE 18321-76/03.2016, Bosch Rexroth Oil Control S.p.A.
Description
Flow is blocked bi-directionally between 1 and 2, until
pressure at either 1 or 2 rises above the combined pressure
of the spring bias, plus pressure at 3. The poppet is
balanced between pressures at 1 and 2 with a 1:1 area
ratio, and held locked by pressure at 3 in a 2:1 ratio versus
either 1 or 2.
Logic element, direction control
