The Sun Hydraulics DNDCXCE512 (DNDCXCE512) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency fluid control. It features a spring-centered neutral position and operates by energizing coil A or B to direct flow between specified ports. Specifically, when coil A is activated, fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), ensuring robust performance in demanding applications. This valve is unique in its design as it does not require any minimum hydraulic pressure for operation due to its direct actuation mechanism. It supports a variety of hydraulic circuit configurations and includes EPDM seals suitable for systems using phosphate ester fluids while cautioning against exposure to petroleum-based substances. The wet armature design allows the working fluid to cool the armature but may affect certain fluids like water-glycol mixtures over time. The DNDCXCE512 offers versatility with various coil termination and voltage options, including those with surge protection. Its high-efficiency solenoid provides substantial spool actuating force per watt consumed, enhancing reliable valve shifting capabilities. Compatible with Sun Series 1 solenoid products, the coils can be mounted bidirectionally on the tube and offer IP69K-rated connector options for enhanced environmental protection. Incorporating Sun's floating style construction minimizes internal binding risks due to installation torque variations or machining differences in cavity/cartridge interfaces. With a capacity of handling up to 5 gpm (20 L/min) and a typical response time of around 50 ms, this valve is designed for efficient and reliable performance in various 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.
