SF20-22

NUT

Overview

Description

A solenoid-operated, 2 way, normally closed, poppet-type, screw in hydraulic cartridge valve, designed to function as a load holding or blocking valve in applications requiring low internal leakage at high pressure. When de-energized, the SF20-22 acts as a check valve, allowing flow to pass from port 1 to port 2, while blocking flow in the reverse direction. When energized, the poppet lifts to open the port 2 to port 1 flow path. In the energized mode, flow is also allowed from port 1 to port 2

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.
  • Corrosion-resistant plating.
  • Industry common cavity.
