The Sun Hydraulics DNCALAN297 (DNCALAN297) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions to minimize oil loss during shifting, which is particularly beneficial in pilot control circuits. With a robust design that includes a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, this valve ensures reliable operation without the need for minimum hydraulic pressure. The DNCALAN297 is engineered with EPDM seals suitable for systems using phosphate ester fluids, though these seals must be protected from exposure to petroleum-based substances. Its wet armature design allows the working fluid to surround the armature, potentially affecting fluid integrity under prolonged energization due to heat exposure. The valve's efficient magnetic design delivers a high spool actuating force per watt expended, ensuring consistent and reliable valve shifting. This model accommodates a wide range of coil termination and voltage options, including configurations with surge protection. Coils are interchangeable across Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include an IP69K rating option for coil connectors and availability of weatherized coils and kits for enhanced environmental protection. Sun Hydraulics has incorporated their floating style construction into the DNCALAN297 to minimize internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. The valve offers a maximum flow capacity of 8 gpm (30 L/min) and operates efficiently with a typical response time of 50 ms and maximum leakage at 110 SUS (24 cSt) being only 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). This model is also designed for easy installation with specific torque requirements and manual override capabilities, making it adaptable and user-friendly for various hydraulic applications.

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.
