DESCRIPTION
A solenoid-operated, 4-way, 3-position, direct-acting, spool-type, motor spool, screw-
in hydraulic cartridge valve.
OPERATION
When de-energized, the SV08-47D blocks flow to 3, while allowing flow from 2 to 1,
and from 4 to 1. When coil #1 is energized, flow is allowed from 3 to 4, and from
2 to 1. When coil #2 is energized, flow is allowed from 3 to 2, and from 4 to 1.
In circuits where work port flows are unequal due to cylinder ratios, the higher return
flow should be directed to port 2.
While 1 may be fully pressurized, it is not intended for use as the valve’s inlet.
Operation of Manual Override Option: To override, push the knurled button to
activate the coil #2 (S2) function, or pull the knob to activate the coil #1 (S1) function.
FEATURES
• Continuous-duty rated solenoid.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• All ports may be fully pressurized.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Compact size.
• Optional waterproof E-Coils rated up to IP69K.
• Manual override option.
