SOLENOID VALVES
SV20-S39 Poppet-Type High-Flow Blocking, N.O.
DESCRIPTION
A solenoid-operated, normally open, poppet-type, screw-in hydraulic cartridge valve,
designed to operate as a bidirectional load-holding or blocking valve in high fl ow
circuits requiring low internal leakage.
OPERATION
When the SV20-S39 is energized, it functions as a check valve, allowing fl ow from ➀
to
➁ while blocking fl ow from ➁ to ➀. When de-energized, the poppet lifts to open the
➁ to ➀ fl ow path while also allowing fl ow from ➀ to ➁. Port ➂ is typically connected to
the reservoir.
FEATURES
• Continuous-duty rated solenoid. • Manual override option.
• Hardened precision spool and cage. • Optional E-Coils rated up to IP69K.
• Optional coil voltages and terminations. • Unitized, molded coil design.
• Effi cient wet-armature construction. • Industry common cavity.
• Cartridges are voltage interchangeable.
