SP08-47DL

PROPORTIONAL SOLENOID VALVE 3 POSITION, 4 WAY, CLOSED CENTER SPOOL

Overview

Description

A solenoid operated, direct acting, 3 position, 4-way, closed center spool, proportional directional control. It is a screw in hydraulic cartridge valve for use with general purpose hydraulic fluids. Manual override feature is available as an option

Operation

When de-energized, the SP08-47DL blocks flow to port 3, while allowing flow from port 2 to port 1 and port 4 to port 1. When coil #1 is energized, flow is allowed from port 3 to port 4, and from port 2 to port 1. When coil #2 is energized, flow is allowed from port 3 to port 2, and from port 4 to port 1

note: that while port 1 may be fully pressurized, it is not intended for use as the valve's inlet

Features

  • Continuous-duty rated solenoid.
  • Hardened precision spool and cage for long life.
  • Optional coil voltages and terminations.
  • Manual override option.
  • Optional waterproof E-Coils rated up to IP69K.
  • Efficient wet-armature construction.
  • Cartridges are voltage interchangeable.
  • Good linearity and hysteresis.
  • Industry-common cavity.
