Catalog HY14-2550/US Proportional Directional Control Valves

Technical Information Series D*1FW and D*1FT

General Description
The D*1FW/D*1FT series two-stage pilot operated
proportional directional control solenoid valves are
available with or without integrated control electronics.
A
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.
• Optional integrated control electronics with ramp
adjustment.
• Low leakage.
• Progressive flow characteristics for improved low flow
resolution.
• Spring centered main stage spool.
• Wide selecton of spool options and flow capacity.
• 2:1 ratio spool options.
