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 operated, differential area
,relief function is activated and flow is relieved from C2 to V2. With pilot pressure at P, 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 drained to
V2, and any back-pressure at V2 is additive to the pressure setting in all functions.Through port C3,an incorporated shuttle
valve directs either P or V2 line pressure to the spring actuated brake for brake opening. -
