The Sun Hydraulics DNDCXTE71219 (DNDCXTE71219) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-performance hydraulic systems. This valve is spring-centered to a neutral position and allows for precise control of hydraulic flow with its unique solenoid design. When coil A is energized, the flow direction is from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects the flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for fatigue resistance under pressures up to 5000 psi (350 bar), ensuring durability in demanding applications. This valve operates without requiring a minimum hydraulic pressure, making it versatile for various setups. It features a wet armature design that immerses the armature in the working fluid, which can help dissipate heat generated by the coil but may affect certain fluids like water-glycol mixtures over prolonged use. The DNDCXTE71219 valve offers multiple coil termination and voltage options, including configurations with surge protection, enhancing adaptability to different electrical environments. The cartridge's floating style construction minimizes internal binding risks due to installation torque or machining variations. It has a capacity of up to 5 gpm (20 L/min) and maintains reliable performance with a typical response time of just 50 ms. The valve's maximum leakage rate at standard viscosity is minimal at only 10 in\u00b3/min (160 cc/min) under high pressure conditions. Additionally, it supports high switching frequencies of up to 15,000 cycles per hour. With interchangeable coils compatible with other Sun Series 1 products and weatherized options available for environmental protection, this spool valve provides robust functionality across diverse hydraulic applications.

This direct acting, solenoid-operated, 4-way, 3-position spool valve is spring centered to the neutral position. When coil A is energized, the flow is from port 3 (P) to port 2 (A) and from port 4 (B) to port 1 (T). When coil B is energized, the flow is from port 3 to port 4 and from port 2 to port 1.

  • 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.
  • In differential flow circuits, the higher return flow should be directed through port 2 (A) to port 1 (T).
  • Cartridges 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.
