While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics DNCATLV (DNCATLV) is a solenoid-operated, 4-way, 2-position cartridge that functions as a direct-acting, balanced spool directional valve. Designed with a closed transition between positions, it significantly minimizes oil loss during shifts, making it particularly beneficial for pilot control circuits. This valve operates with port 3 as the inlet and port 1 as the tank; although reverse flow is possible, it is not recommended due to performance limitations. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring robust service capability. Notably, this valve requires no minimum hydraulic pressure for operation and features EPDM seals suitable for systems utilizing phosphate ester fluids; these seals are incompatible with petroleum-based substances. The wet armature design allows the working fluid to surround the armature, which can be affected by heat from the coil if energized for extended periods\u2014potentially impacting certain fluids like water-glycol mixtures over time. The DNCATLV offers various coil termination and voltage options while maintaining compatibility with other Sun Series 1 solenoid products. It features a high-efficiency solenoid design that provides significant spool actuating force per watt expended, enhancing reliable valve shifting. Coil connector options offer protection ratings up to IP69K, and additional weatherized coils are available for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or cavity machining variations. With a capacity of 8 gpm (30 L/min) and maximum operating pressure of 5000 psi (350 bar), this model offers a typical response time of 50 ms and supports switching frequencies up to 15,000 cycles per hour. Weighing .60 lb (0.30 kg), its compact design includes features like manual override capabilities and interchangeable coils for versatile application requirements.

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.
