Catalog MSG14-2550/US Proportional Directional Control Valves
Technical Information Series D*9FF
General Description
Series D*9FF main-stage, pilot operated, proportional
A 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.
Features
• Standard DIN/ISO/CETOP/NFPA interfaces
• Progressive flow characteristics for improved low flow
resolution
• Spring centered main stage spool
• 2:1 ratio spool options
