DG5S4-02 Series

DG5S4-02 design Solenoid Controlled Pilot Operated Directional Valves

eaton dg5s4-02

Series 02 two–stage directional valves are designed to meet the requirements of high performance, precision industrial hydraulic systems operating at pressures to 210 bar (3000 psi) and flows to 130 l/min (34 USgpm), depending on spool type (ref. maximum flow curves on page 4). Mounting surface is NFPA D05/ISO–05 with X–Y auxiliary ports.

Two–stage 02 valves (with additional pilot and drain ports) feature tapered main spool lands which permit faster operation with less hydraulic shock. Their close spool–to–bore tolerances also have minimum clearance for low internal leakage without the necessity of selective assembly.

Advanced design pilot valves provide reduced power consumption without any sacrifice of valve performance. Quiet, long life solenoids can be replaced quickly without disturbing the hydraulic circuitry for easy maintenance. These pilot valves create a high margin of shift force that can overcome spool friction occasionally caused from dirt or other contaminants. The manual override is standard for quick start–ups.

Rated Pressure

Ports P, A, B & T (external drain) 210 bar (3000 psi)

Port T (internal drain) 100 bar (1500 psi)

Fluid and Seals

Buna N seals are standard and are compatible with water glycol water–in–oil emulsions, high water base fluids, and petroleum oils. For phosphate ester, fire resistant fluids, viton seals (symbol “F3”) must be used. Maximum operating pressure for high–water base fluids is 1000 psi.

Filtration

For satisfactory service life of these components in industrial applications, use of full flow filtration to provide fluid which meets ISO cleanliness code 18/15 or cleaner, OFP, OFR and OFRS Vickers series filters are recommended.

Viscosity Range

75 to 600 Ssu (15 to 128 cSt)

Operating Temperature Range

–18 to 66 C (0 to 150 F)
