The Sun Hydraulics DNDCXBN528 (DNDCXBN528) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency and reliable operation in hydraulic systems. Featuring a spring-centered neutral position, this valve allows flow from port 3 P to port 2 A and from port 4 B to port 1 T when coil A is energized; alternatively, energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), ensuring durability under demanding conditions. This valve requires no minimum hydraulic pressure for operation, making it versatile for various applications. In differential flow circuits, directing the higher return flow through port 2 A to port 1 T optimizes performance. The valve employs a wet armature design where the working fluid surrounds the armature, which can be affected by heat generated during prolonged coil energization. Users should be cautious with fluids like water-glycol mixtures that may degrade over time due to heat exposure. The DNDCXBN528 offers various coil termination and voltage options with or without surge protection and features interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. Constructed with Sun's floating style design, this valve minimizes internal part binding risks due to installation torque or cavity-cartridge machining variations. It has a capacity of up to 5 gpm (20 L/min) and supports a maximum operating pressure of 5000 psi (350 bar). Typical response time is approximately 50 ms, with maximum valve leakage at specified conditions being minimal. This robust valve supports a high switching frequency of up to 15,000 cycles per hour and offers reliable performance across diverse applications requiring precise control over hydraulic fluid direction and flow rates.

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.
