The Sun Hydraulics DNDCXWE624N (DNDCXWE624N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high efficiency and reliability. This valve is spring-centered to the neutral position and offers precise flow control depending on the coil energized. When coil A is activated, flow occurs from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. Notably, this valve is capable of operating without a minimum hydraulic pressure requirement due to its direct actuation. The solenoid tube assembly of the DNDCXWE624N is engineered for fatigue resistance at pressures up to 5000 psi (350 bar), making it suitable for demanding applications. It features a wet armature design that ensures operational longevity but requires consideration of fluid compatibility due to potential heat exposure. Particularly, EPDM seals are compatible with phosphate ester fluids but can degrade if exposed to petroleum-based substances. This model also boasts a high-efficiency magnetic solenoid design which enhances spool actuation force per watt consumed, ensuring dependable valve shifting. The interchangeable coils are compatible with other Sun Series 1 solenoid products and offer various termination and voltage options, including configurations with surge protection and weather resistance rated up to IP69K. The DNDCXWE624N incorporates Sun's floating style construction that reduces internal binding risks caused by excessive installation torque or machining variations in cavities or cartridges. Its capacity stands at 5 gpm (20 L/min), with a typical response time of around 50 ms. The valve\u2019s maximum leakage rate at standard conditions is approximately 10 in\u00b3/min (160 cc/min). For maintenance convenience, Viton seal kits are available for both the cartridge and coil components.

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.
