Proportional Directional Valves, Series LVS

With the LVS hydraulic valve, designers can now create those mobile-machine control systems that previously have been difficult to master. Its consistent design as a system of valve modules means exceptional adaptability.

The integral auxiliary functions and high power density make the LVS not only a highly adaptable modular valve, but also a very compact one. LVS valve blocks can be configured for both fixed- and variable-displacement pumps.

Advantages

• Savings in energy costs due to low pressure losses.

• Reliable supply of flow, because the proportional flow-sharing principle ensures that all functions can be operated even in the under-supply zone.

• Oscillation-stable even in critical applications, preventing machine breakdowns.

• One valve-block solution for all pump systems.
