■ Minimal hysteresis.
■ One piece cartridge housing ensures internal concentricity.
■ Coil: Waterproof, hermetically sealed, requires no O’Rings;
Symmetrical coil can be reversed without affecting performance.
■ Nonmagnetic spool and housing assembly.
OPERATION
Analog proportional pressure regulating valve,
regulates pressure at port 2 relative to the soleniod current.
Regulated pressure is virtually independent of input pressure.
The soleniod force is balanced against the regulated pressure
that provides feedback to maintain the spool’s position. Typical
applications are the control of transmission clutches or cylinders.
