SP08-24 Valve

SYMBOL:
SP08-24 Valve symbol

 

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_pdf.

FEATURES
• 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.

RECOMMENDED ELECTRONIC CONTROLLERS
The EVDR Series controllers are recommended for use with most HydraForce proportional
valves. These newer electronic controllers are versatile, reliable, and easily configured and
customized for a wide range of applications.
