SAE08-3
DESCRIPTION
A solenoid valve operated, 4-way, 2-position, spool-type, direct-acting, screw-in hydraulic cartridge valve. In the de-energized mode
the SVA0.S08 flow paths are 1 to 4 and 3 to 2. In the energized mode the valve’s spool shifts to open 1 to 2 and 3 to 4. The rigid
design using a 1-piece body contributes to minimize the effect of eccentricities in cavity and provides great reliability. All ports are
connected at crossover. Low pressure drop thanks to optimized paths.
