A proportional solenoid-operated, 2-way, piloted, poppet-type, normally closed, screw-in hydraulic cartridge valve for low-leakage blocking and load-holding in high pressure applications requiring low internal leakage.
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.
