D*9FF Proportional
Directional Control Valve
Series D*9FF main-stage, pilot operated, proportional directional control valves are operated with remote hydraulic hand controllers. Valves are available in sizes NG10 (CETOP 5), NG16 (CETOP 7), NG25 (CETOP 8) and NG32 (CETOP 10). Typical applications include reproducible control of actuator speed in rapid/slow speed profiling, and smooth acceleration and deceleration performance.
VP170 Load-Sense
Directional Control Valve
The VP170 valve is an excellent choice for applications with pump input flows from 130-230 LPM (35-60 GPM). The VP170 uses contemporary flow-sharing technology to address the productivity problems associated with pump over-demand conditions. Targeting construction, forestry and refuse markets, these values are ideal for wheel loaders, dozers, cranes, feller bunchers, harvesters, forwarders, log loaders and automated-side loaders. The modular design of the VP170 enables hardware to be added or removed, depending upon the application. For example, it can be configured for load-sense only, load-sense pressure compensation, and with or without induced-load protection. For added cost control, the VP170 uses all of the spool positioners, relief valves and tie bolts from other field-proven Parker valves.
