SF20-23 Poppet, 2-Way, Normally Open (SF20-23)
A solenoid-operated, 2-way, normally open, piloted poppet-type, screw-in hydraulic cartridge valve, intended to act as a blocking or load-holding device for applications requiring low internal leakage.
Product Operation
When energized, the SF20-23 acts as a check valve, allowing flow from ➀ to ➁, while blocking flow from ➁ to ➀When de-energized, the cartridge’s poppet lifts to open the ➁ to ➀ flow path. In this mode, bidirectional flow is allowed.
Product Features
• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
