Parker VP170 Proportional Directional Control Valve with Load-Sense Pressure Compensation with Load Sharing

The VP170 can be configured either as pressure compensated load-sense (PCLS) or as load-sense (LS). Both have the flexibility of sectional construction. The PCLS work section has its own compensator, so that speed control of multiple functions is achieved, regardless of changes in pressure or engine rpms. The key technology integrated into the VP170 is flowsharing. In pump over-demand conditions, flow-sharing benefits machine productivity by maintaining the speed relationship of the selected functions, but at a reduced speed. This allows the operator to maintain the rhythm of the machine.

Benefits

Flow-sharing for improved productivity, safety and operator comfot
Load-sense pressure compensated for improved system efficiency and fuel savings
Modular design enables better match between cost and value.
Low loop pressure drops for reduced horsepower consumption
Low pressure regeneration to solve cavitation problems of premature component failure

Ideal for wheel loaders and dozers, cranes, forestry, refuse, snow and ice and distribution
