SV90-G40R

SOLENOID CARTRIDGE VALVE 2-POSITION, 4-WAY

Overview

Description

The SV90-G40RX is a direct-acting, spool-type, 2-position, 4-way directional control valve. It is a drop-in, flange mounted, cartridge type valve for use with general purpose hydraulic fluids. The coil is an integral part of the valve and is not serviceable

Operation

When de-energized, the SV90-G40RX allows flow from port 3 to port 4, and from port 2 to port 1. When energized, the spool shifts to allow flow from port 3 to port 2, and from port 4 to port 1

Features

  • Bi-directional operation.
  • Reduced leakage.
  • Low pressure drop
  • Economical drop-in style.
  • Fast response.
  • Corrosion-resistant plating.
  • Inlet port screen option for additional resistance to contamination.
  • Higher flow capacity at lower temperatures.
  • Integral waterproof coil standard. See page 3.400.1 for a description of tests conducted to verify coil waterproofing.
  • Coil voltage range from 10 to 28 VDC.
  • Top-mounted coil with several push-on termination options.
  • Round flange with optional mounting plates provides more options for orientation.
  • Retrofit mounting options also available.
