SP08-24 Valve

SP08-24 Valve symbol


A proportional solenoid-operated, 2-way, spool-type, normally closed, screw-in
hydraulic cartridge valve designed to operate as a bi-directional metering valve.

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_pdf.

• Industry-common cavity.
• Continuous-duty rated coils.
• Efficient wet-armature construction.
• Allow bi-directional flow when fully energized.
• Optional waterproof E-Coils rated up to IP69K.
