The Sun Hydraulics DNCALAN628 (DNCALAN628) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve ensures a closed transition between positions, minimizing oil loss during shifting\u2014a crucial feature for maintaining efficiency in pilot control circuits. With a robust design that allows for port 3 to be used as the inlet and port 1 as the tank, the DNCALAN628 offers reliable performance even though reverse flow is possible but not recommended due to potential performance variations. The valve's solenoid tube assembly is fatigue rated for demanding 5000 psi (350 bar) service conditions, ensuring durability and longevity. It operates without requiring a minimum hydraulic pressure, which enhances its versatility across various applications. The wet armature design of the DNCALAN628 means that the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization conditions; thus, it's important to consider fluid characteristics when using this valve. For environments with specific fluid requirements, cartridges configured with EPDM seals are compatible with phosphate ester fluids but should avoid exposure to petroleum-based substances to prevent seal damage. Additionally, Sun Hydraulics has made available an array of coil termination and voltage options for this model\u2014some equipped with surge protection\u2014to cater to diverse operational needs and environments. The DNCALAN628 also features interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Its unique magnetic design enhances solenoid efficiency by maximizing spool actuating force per Watt expended. The construction includes Sun's floating style mechanism which helps prevent internal parts binding due to excessive installation torque or cavity/cartridge machining variations, further ensuring reliability and optimal performance under varied installation conditions.

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.
