Housing modularity is used to provide different mount- SAE C)( different porting (rear port, side port, or a combina- tion), and different shafts Thrushaft design is used so that multiple pumps can hydraulic system with a single drive input. A separate port plate is modular system providing low speed, high speed, low noise, or motor operation from the same housings- Most of these changes designed to manifold mount Not only does this feature provide field changeability, typical hydraulic controls proportional controls.

As con be seen on the drawings to fhe left, trie control« completely balanced with the force locations on on axis perpendicular to the pivot axis and located midway between the pivot points. This design eliminates the strong binding, cocking, and sticking forces present in other designs. The resulting benefits ore decreased hysteresis, better stability, and lower minimum pressures fi e* minimum compensating pressure TYPICAL CONTROLS AND COMBINATIONS TORQUI |HP| PRESSURE.

As con be seen on the drawings ro the right, the control are mounted with a simple manifold design with the connections to the two control pistons, H.P, port and tank accomplished through drillings in the casting. With this with the inherent stability of the balanced two pitton design allows great control flexibility by simply adding manifolded sented below, but, many more ON.'OIF CONTROL SOLENOID StLCCTfD- SOtlNOlO MUCIID- FLOW/ LOAD SOLENOID SOFT START.
