MVB
Xeriwell or Others
Eaton’s MVB series hydraulic motors are fixed displacement inline piston motors, offering a choice of five torque ratings. They operate at speeds ranging from 100 to 3600 r/min and can handle pressures up to 210 bar (3000 psi).
Key Features:
1）Fixed Displacement Design: Ensures consistent performance across various applications.
2）Wide Speed Range: Operates efficiently between 100 to 3600 r/min, accommodating diverse operational needs.
3）High-Pressure Capacity: Handles pressures up to 210 bar (3000 psi), suitable for demanding tasks.
4）Multiple Torque Ratings: Offers five torque options, providing flexibility in system design.
5）Durable Construction: Built to withstand rigorous operating conditions, ensuring longevity.
The MVB series is ideal for applications requiring reliable and consistent hydraulic power, such as industrial machinery and mobile equipment.
Type: MVB5, MVB10
