DESCRIPTION

A proportional solenoid-operated, 2-way, spool-type, normally closed, screw-in

hydraulic cartridge valve designed to operate as a bi-directional metering valve.

OPERATION

When de-energized, the SP08-24 blocks flow in both directions. When the coil is

partially energized, the valve begins to throttle flow. When fully energized, the valve

opens to allow full, bi-directional flow.

Note: If low voltage is expected on the machine, 12 or 24 volt systems will

require the use of 10 volt or 20 volt coils respectively. See “SP Valves and Coil

Operating Parameters,” page 2.002.1.

FEATURES

• Industry-common cavity. • Efficient wet-armature construction.

• Continuous-duty rated coils. • Optional waterproof E-Coils rated up to IP69K.
