Proportional Directional Control Valves
A
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.
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.
