DESCRIPTION
A solenoid-operated, four-way, three-position, direct-acting, spool-type,
tandem center, screw-in hydraulic cartridge valve.
OPERATION
When de-energized, the SV08-47A blocks cylinder ports, while allowing flow from 3 to
1. When coil #1 is energized, flow is allowed from 3 to 2, and from 4 to 1. When coil
#2 is energized, flow is allowed from 3 to 4, and from 2 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 knob to activate
the coil #2 (S2) function; 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.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
