DNDB : Value Series 4-way, 2-position, solenoid-operated directional spool valve - 3600 psi (250 bar)
Technical Features [ + ]

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.

  • This valve is direct actuated and requires no minimum hydraulic pressure for operation.
  • The solenoid tube assembly is fatigue rated for 3600 psi (250 bar) service.
  • Port 3 is the preferred inlet for this valve.
  • This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

Only external seals are serviceable.  Sun offers replacement seal kits for all cartridge models. The applicable kit part number can be found in the product page's Technical Data table or by using our Cartridge Seal Kit search function located under Accessories. Please note: Converting the external seals from one material to another does not ensure fluid compatibility with that material due to the existence of internal seals within the cartridge.
Flow is rated at 200 PSI pressure drop.
Notes [ + ]
  • Please verify cartridge clearance requirements when choosing a Sun manifold. Different valve controls and coils require different clearances.
  • An additional 2.00 inches (50,8 mm) beyond the valve extension is needed for coil installation and removal.
