DESCRIPTION
A solenoid-operated, 5-way, 3-position, motor-spool-type,
screw-in hydraulic cartridge valve with integral load sense port.
OPERATION
When de-energized, the SV08-58D blocks inlet flow at port 5 while load sense at port 1 is vented to port 3, and ports 2 and 4 are connected to port 3. When coil #1 is energized, flow is allowed from 5 to 2 and from 4 to 3. When coil #2 is energized, flow is allowed from 5 to 4 and from 2 to 3.
Load sense at port 1 is connected to port 5 when spool is in the shifted positions.
FEATURES
• Continuous-duty rated solenoid.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Optional waterproof E-Coils rated up to IP69K.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Compact size.
