RE 18307-52/03.2016, Bosch Rexroth Oil Control S.p.A.
Characteristic curve
Description
When pressure at V2 rises above the spring bias pressure,
the check seat is pushed away from the piston and flow is
allowed from V2 to C2. When load pressure at C2 rises
above the pressure setting, the direct-acting, differential
area, relief function is activated and flow is relieved from
C2 to V2. With pilot pressure at V1–C1 , the pressure
setting is reduced in proportion to the stated ratio of the
valve, until opening and allowing flow from C2 to V2. The
spring chamber is vented to atmosphere allowing operation
of all functions independent of back-pressure at V2.
Note: port identified with M are not protected with
calibrated orifice but in direct connection with pressure
channels.
