The Sun Hydraulics DNCALWN514 (DNCALWN514) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve features a closed transition between positions, which significantly reduces oil loss during shifting\u2014a crucial aspect in pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank, though reverse flow is not recommended due to potential performance issues. The solenoid tube assembly is fatigue-rated for continuous service at up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve does not require a minimum hydraulic pressure for operation, making it versatile across various applications. The DNCALWN514 employs a wet armature design, allowing working fluid to surround the armature and be exposed to heat from the coil. While this enhances efficiency, users should consider fluid compatibility as some fluids may degrade over time when exposed to heat. The valve is compatible with EPDM seals for systems using phosphate ester fluids; however, exposure to petroleum-based substances will damage these seals. Offering flexibility in installation, the valve supports various coil termination and voltage options, with interchangeable coils that are also compatible with other Sun Series 1 solenoid products. The coils can be mounted in either direction and offer protection ratings up to IP69K for enhanced environmental resistance. Additionally, Sun's floating style construction minimizes binding risks due to installation torque or machining variations. With a capacity of 8 gpm (30 L/min) and a typical response time of 50 ms, this valve provides reliable performance with minimal leakage at maximum operating conditions. Its robust design supports high switching frequency up to 15,000 cycles per hour and manual override capabilities for added control flexibility in demanding hydraulic systems.

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.
