SV08-47A Valve

SYMBOL:
SV08-47A Valve symbol
DESCRIPTION
A solenoid-operated, 4-way, 3-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 S1 is energized, flow is allowed from 3 to 2, and from 4 to 1. When coil S2 isenergized,
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 button toactivate 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.
• Manual override option.
• Optional waterproof E‑Coils rated up to IP69K.
• Efficient wet-armature construction.
• All ports may be fully pressurized.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Industry-common cavity – compact size.
