The Sun Hydraulics DNCALLN248 (DNCALLN248) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Its closed transition between positions minimizes oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to potential performance degradation. The solenoid tube assembly is engineered for durability, rated for fatigue service up to 5000 psi (350 bar). This valve operates without needing any minimum hydraulic pressure and features EPDM seals suitable for systems using phosphate ester fluids, though these seals are incompatible with petroleum-based substances. The DNCALLN248 employs a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil. Users should note that prolonged coil energization may cause certain fluids to degrade at higher temperatures, potentially forming varnishes that impair cartridge function. A variety of coil termination and voltage options are available, some with surge protection. The solenoid's efficient magnetic design ensures high spool actuating force per watt expended, promoting reliable valve operation. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, coil connector options offer ratings up to IP69K for enhanced environmental protection. The DNCALLN248 incorporates Sun's floating style construction to reduce the risk of internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into cavity T-31A and belongs to Series 1 with a capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar). This model has a typical response time of 50 ms and a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar).

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.
