Description  

Shut circuit
Sequence 32
Dimensions seventy one, ninety
Nominal pressure 5800 psi (400 bar)
Optimum pressure 6500 psi (450 bar)
Manage system: (HW) Proportional manage hydraulic, mechanical servo, hexagon shaft with lever to the rear.
(EP) Proportional management electrical, with emergency actuation and spring return.
 
For the drum push in cellular concrete mixers A4VTG071, A4VGT090 collection.
-Variable axial piston pump of swash plate layout for hydrostatic drives in closed circuit
-The movement is proportional to the drive pace and displacement.
-The flow raises as the angle of the swash plate is modified from zero to its optimum benefit.
-Stream direction modifications effortlessly when the swash plate is moved by way of the neutral position.
-Two force-reduction valves are offered on the high pressure ports to defend the hydrostatic transmission (pump and motor) from overload.
-The substantial-force reduction valves also purpose as enhance valves.
-The integrated enhance pump acts as a feed pump and handle strain offer.
-The highest enhance strain is restricted by a constructed-in boost force-relief valve.
-Tapered shaft option for immediate travel shaft yoke set up.
