A solenoid-operated, 2-way, normally closed, piloted poppet-type, screw-in hydraulic
cartridge valve, intended to act as a blocking or load-holding device for low flow circuits.
When de-energized, the SF08-20 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. In this mode, flow from 1 to 2 is severely restricted. If this path is
required, see model SF08-22, page 1.042.1.
