HSP16-20 Valve

SP08-20 Valve symbol


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. This valve can be ordered with a linear metering option (see Performance Charts) or a
manual override option.

When de-energized, the HSP16-20 blocks flow from ports 2 to 1. In this mode, the cartridge will
allow flow from ports 1 to 2 after overcoming the spring forces (see performance graph). When
energized, the valve will allow flow from ports 2 to 1 while severely restricting flow from ports 1 to 2.
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.
