The Sun Hydraulics DNDCXAE (DNDCXAE) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for reliable performance in hydraulic systems. This valve is spring-centered to the neutral position and offers two distinct flow paths: energizing coil A directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. It features a solenoid tube assembly fatigue rated for service up to 5000 psi (350 bar) and requires no minimum hydraulic pressure for operation. The valve is ideal for differential flow circuits where higher return flow should be directed through port 2 A to port 1 T. The DNDCXAE utilizes a wet armature design, which means that the working fluid surrounds the armature and absorbs heat generated by the coil. This can affect performance if the coil remains energized for extended periods, particularly with fluids like water-glycol mixtures that may degrade at high temperatures. The valve offers various coil termination and voltage options, with or without surge protection, ensuring compatibility with different system requirements. This model incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations in cavity/cartridge assemblies. It has a capacity of up to 5 gpm (20 L/min) and a typical response time of approximately 50 ms. The maximum valve leakage at specified conditions is limited to ensure efficiency. Additionally, the DNDCXAE supports high switching frequency up to 15,000 cycles per hour. Coils are interchangeable within Sun's Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options provide ratings up to IP69K for enhanced environmental protection, making this valve suitable for demanding applications where reliability is crucial.

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.
