LOAD HOLDIND CARTRIDGES
Load holding cartridge valves with internal and external pilot are used to control overrunning load, The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot- assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio.
