Technical Feature
OPERATION:
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 Pil ， the pressure setting is reduced in proportion to the
stated ratio of the valve, until fully open with free-flow from C2 to V2 ． The spring chamber is
drained to V2 ， and any back-pressure at V2 is additive to the pressure setting in all functions. -
