The Sun Hydraulics DNCAMJN512 (DNCAMJN512) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This directional valve is engineered with a closed transition between positions, which significantly reduces oil loss during shifting\u2014an essential feature for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, though reverse flow is possible but not recommended due to potential performance limitations. Designed for robust applications, the solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), and it operates without needing any minimum hydraulic pressure. This model incorporates EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids could damage these seals. It utilizes a wet armature design where the working fluid cools the coil-generated heat. Users should note that fluids like water-glycol mixtures can degrade over time at elevated temperatures, potentially affecting cartridge function. The solenoid's magnetic design enhances efficiency by delivering high spool actuating force per watt of power used, ensuring reliable operation. The DNCAMJN512 offers multiple coil termination and voltage options, including configurations with surge protection. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted bidirectionally on the tube. Coil connectors are rated up to IP69K for enhanced environmental protection. The valve features Sun's floating style construction to minimize internal part binding due to installation torque or machining variations in cavity/cartridge interfaces. Specifications include a cavity size of T-31A, series 1 capacity of 8 gpm (30 L/min), typical response time of 50 ms, maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), and switching frequency up to 15,000 cycles per hour. The valve also includes manual override capabilities and specific installation torque requirements for optimal performance.

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.
