The Sun Hydraulics DNDCXAN528 (DNDCXAN528) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient fluid control in hydraulic systems. This valve is spring-centered to maintain a neutral position and allows for precise flow direction when energized. Specifically, 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. With a fatigue rating for service up to 5000 psi (350 bar), this valve is suitable for high-pressure applications without requiring minimum hydraulic pressure for operation. It features a wet armature design that enhances the efficiency of the solenoid by surrounding the armature with working fluid, which can be crucial for prolonged coil activation periods. The valve's construction includes EPDM seals compatible with phosphate ester fluids, although they may degrade if exposed to petroleum-based substances. The DNDCXAN528 incorporates Sun's floating style construction to minimize internal binding due to installation or machining variations. It offers versatility with various coil termination and voltage options, including configurations with surge protection. The solenoid's high-efficiency magnetic design ensures reliable valve shifting by maximizing spool actuating force per watt expended. Coils are interchangeable across Sun Series 1 solenoid products and can be oriented in either direction on the tube. Additionally, the valve supports weatherized coils and kits for enhanced environmental protection. Technical specifications include a cavity size of T31A, a series designation of 1, a capacity of up to 5 gpm (20 L/min), response times typically around 50 ms, and maximum leakage at specified conditions of approximately 10 in\u00b3/min (160 cc/min). The switching frequency capability reaches up to 15,000 cycles per hour.

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.
