We reserve the right to change specifications without and SpecificationsPerformance data is typical with fluid at 21,8 cST (105 SUS) and 49 C (120 F)Typical application pressure (all ports) 210 bar (3000 psi)Maximum Regenerative flow 57 L/min (15 USgpm) Regeneration diminishes progressively above setting of CBV1-10 Temperature range -40 to 120 C (-40 to 248 F)Fluids All general purpose hydraulic fluids such as: MIL -H-5606, SAE 10, SAE 20, standard Valve package provides means for fast exten-sion of a cylinder at low pres-sure without additional pump flow.

2 This package diverts rod end flow to the head end in order to accelerate the load. When the load induced pres-sure reaches a predetermined level, the Valve closes off. Rod end oil is automatically divert-ed to tank and the full pump pressure is applied, allowing maximum force to develop at lower applying pressure sensitive Regenerative valves consider the following: Rod to diameter ratio. The pressure required to move a cylinder. Losses due to high flows and seal friction may prevent a circuit from staying in kick out of regen-erative operation made via load pressure sensing. Tamper proof and adjustable pres-sure setting options.

3 Provides a smooth transition and decrease of the Regenerative flow through use of a counter-balance Valve . Provides manual override on POC cartridge to lower the load in the event of power loss.
