Operation
When pressure at V2 rise 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 rise above the pressure setting,the direct-acting,differental
area relief function is activated and flow is relieved from C2 to V2.With pilot pressure setting is reduced in
proportion to the stared 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 function.
