Eaton Hydraulic Motors Valve-In-State Series

The VIS ( Valve-in-Star ) Motors are the next step in the evolution of the low speed high torque (LSHT) hydraulic motors. The IS design provides inherent improvements over other types of LSHT hydraulic motor valving which results in a more compact package with better efficiency and higher pressure capability. These improvements have shown significant packaging and performance advantages in applications such as skid steer loaders, mini excavators, trenchers and logging equipment. VIS motors are primarily intended for use in closed loop circuit applications.
