DESCRIPTION
A proportional solenoid-operated, 2-way, piloted, normally closed, , poppet-type, screw-in hydraulic cartridge valve for blocking or load-holding in high pressure applications requiring low internal leakage.
OPERATION
When de-energized, the HSP16-20 acts as a check valve, allowing flow from 1 to 2, while blocking flow from 2 to 1. When energized, the cartridge’s poppet lifts to open the 2 to 1 flow path. Flow is proportional to current applied to the coil.
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.
