SOLENOID CARTRIDGE VALVE POPPET, 2 WAY, NORMALLY OPEN HIGH PRESSURE

Overview

Description

A solenoid-operated, 2 way, piloted, poppet-type, normally open, screw in hydraulic cartridge valve designed for low leakage in higher pressure load-holding applications.

Operation

When de-energized, the sf08-21xx allows flow from port 2 to port 1. Flow from port 1 to port 2 is severely restricted in this mode. When energized, the valves poppet closes on its seat, blocking flow from port 2 to port 1. In this mode the cartridge will allow port 1 to port 2 flow after overcoming the solenoid force (requires 50 to 150 psi [3,4 to 10,3 bar]).

Features

  • Continuous-duty rated coil.
  • Corrosion-resistant plating.
  • Hardened seat for long life and low leakage.
  • Optional coil voltages and terminations.
  • Cartridges are voltage interchangeable.
  • Unitized, molded coil design.
  • Manual override option.
  • Optional waterproof E-Coils rated up to IP69K.
  • Industry common, compact size.
