New solenoid valve delivers cost-effective load-holding solution

Value Series Directional Valves

The latest addition to Sun's Value Series directional valves, the DTDB is an extremely low-leakage solenoid-operated directional valve suited for load-holding applications with system requirements up to 3600 psi (250 bar). And the new valve is priced for OEM applications, offering more than 30% savings from our standard 5000-psi (350-bar) DTDA.

Value Series DTDB and standard DTDAThis new DTDB is a two-position, two-way direct-acting poppet valve that offers a leakage rate of less than 10 drops/min. at 3000 psi (0,7 cc/min at 210 bar) and is available as normally open or normally closed. It hits a sweet spot, acting as a standalone 8-gpm (30 L/min) valve or the perfect low-cost pilot-valve solution to drive a wide range of Sun logic valves in industrial and mobile applications. And if needed, the standard DTDA offers a higher-pressure, higher-flow upgrade path for more demanding applications.

Unlike low-priced competitors' valves, the DTDB includes all the advantages you expect from Sun — high quality, quick delivery, exceptional support and service — while still keeping prices attractive to the OEM. And as with the other members of the Value Series, they can be used with HCT controllers for flexible system configuration.

Features of the Value Series include:

  • 3600 psi (250 bar) maximum operating pressure
  • 2-position, 2-, 3-, and 4-way operation
  • Poppet-style construction (DTDB) for low leakage
  • Spool-style construction (DLDB, DMDB, DNDB)
  • Flows up to 12 gpm
  • Various coil connector and voltage options, including Deutsch, twin-lead, and ISO/DIN 43650A in both 12 and 24 Vdc
  • Manual override option
