SP08-25 Valve

SYMBOL:
SP08-25 Valve symbol

DESCRIPTION
A proportional solenoid-operated, 2-way, spool-type, normally-closed,
direct-acting, screw-in cartridge valve for bi-directional metering. It can be
specified for diesel engine fuel metering applications.

OPERATION
When energized, the SP80-24 acts as a bi-directional metering valve.
When de-energized, the valve blocks flow in both directions.
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.

• Compatible with diesel fuel types 1 and 2.
• Corrosion-resistant plating.
• Stainless steel options available - consult factory.
• Continuous-duty rated coils.
• Efficient wet-armature construction.
• Optional waterproof E-Coils rated up to IP69K.
