DESCRIPTION
A proportional solenoid-operated, 2-way, bi-directional, poppet-type, normally closed,
screw-in hydraulic cartridge valve for low-leakage blocking and load-holding.
OPERATION
When de-energized, the SP08-22 acts as a check valve, allowing flow from 1 to 2,
while blocking flow from 2 to 1. When energized, the poppet lifts to open the 2 to 1
flow path. Flow is proportional to current applied to the coil. The reverse-flow check
allows unrestricted flow from 1 to 2
when the valve is energized, but this flow is not
proportional to the current.
Note: External circuitry is required to ramp current.
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. • Hardened steel work surfaces.
• Continuous-duty rated coils. • Optional waterproof E-Coils rated up to IP69K
