E-SV08-47B SOLENOID CARTRIDGE VALVE 3 POSITION, 4 PORT OPEN CENTER
SYMBOL
DESCRIPTION
A solenoid-operated, 4-way, 3-position, direct-acting, spool-type, open center, screw-in hydraulic cartridge valve.
OPERATION
When de-energized, the E-SV08-47B allows flow to all ports.
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 pressurize, 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:
* Continous-duty rated coil.
* Hardened seat for long life and low leakage.
* Optional coil voltages and terminations.
* All ports may be fully pressurized.
* Efficient wet-armature construction.
* Cartridges are voltage interchangable.
* Unitized, molded coil design.
* Manual override option.
* Optional waterproof E-Coils rated up to IP69K.
* Industry common cavity.
* Compact size.
