The Sun Hydraulics DNCADBN299 (DNCADBN299) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. It operates with a valve capacity based on port 3 as the inlet and port 1 as the tank, and while reverse flow is feasible, it is not recommended due to potential performance issues. The DNCADBN299 has been engineered to handle a maximum operating pressure of 5000 psi (350 bar) and offers a robust response time of approximately 50 ms. It supports up to 8 gpm (30 L/min) flow capacity and demonstrates maximum valve leakage at an impressive rate of less than 10 in\u00b3/min at 3000 psi. The solenoid tube assembly within this model is fatigue rated for high-pressure conditions, ensuring reliability and longevity in demanding applications. This model incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Its wet armature design allows the working fluid to surround the armature which helps in heat management but requires consideration regarding fluid type due to potential breakdown from prolonged exposure to heat. Sun Hydraulics offers various coil termination and voltage options for this model including designs with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction. The design also includes Sun's floating style construction which reduces risks associated with internal parts binding due to installation variances or cavity/cartridge machining discrepancies. Overall, the DNCADBN299 provides versatile configuration options and reliable performance for hydraulic system applications requiring precise directional control of fluid flow.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.

  • Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
  • The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
  • This valve is direct actuated and requires no minimum hydraulic pressure for operation.
  • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
  • 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.
  • A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
  • The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
  • Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
  • Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
  • 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.
