The Sun Hydraulics DNDCXTE2E24V (DNDCXTE2E24V) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This versatile valve allows for efficient flow control in hydraulic systems. When coil A is energized, it directs flow from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, when coil B is energized, the flow shifts from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly of this valve is engineered for high durability with a fatigue rating suitable for service pressures up to 5000 psi (350 bar). It operates directly without requiring minimum hydraulic pressure, making it adaptable for various applications. This valve is particularly beneficial in differential flow circuits where higher return flows should be routed through specific ports. Its design incorporates EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of the valve ensures that the working fluid surrounds the armature, which can be a consideration if the coil remains energized over long periods due to potential varnish formation in certain fluids. The DNDCXTE2E24V offers multiple coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. Its unique magnetic design provides high efficiency with significant spool actuating force per watt expended. Additional features include weatherized coils and kits for enhanced environmental protection and floating style construction that reduces internal binding risks during installation or machining variations. With a capacity of up to 5 gpm (20 L/min) and response time typically around 50 ms, this valve meets demanding operational requirements efficiently.

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.
