The Sun Hydraulics DNDCXBV528 (DNDCXBV528) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-performance hydraulic systems. This valve is spring-centered to the neutral position and features two operational modes: when coil A is energized, the flow routes from port 3 P to port 2 A and from port 4 B to port 1 T; when coil B is energized, flow shifts from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring durability in demanding applications. It operates without the need for a minimum hydraulic pressure due to its direct actuation design. In differential flow circuits, it is advised that higher return flows are directed through port 2 A to port 1 T. The valve's cartridges with EPDM seals are compatible with phosphate ester fluids but should not be exposed to petroleum-based fluids as these can damage the seals. Featuring a wet armature design, the working fluid surrounds the armature and can be affected by heat generated during prolonged coil energization. The DNDCXBV528 offers various coil termination and voltage options, some with surge protection. Its high-efficiency solenoid design provides reliable valve shifting by maximizing spool actuating force per watt consumed. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Additionally, coil connector options provide ratings up to IP69K for enhanced environmental protection. Incorporating Sun's floating style construction minimizes internal part binding due to excessive installation torque or cavity-cartridge machining variations. The valve has a capacity of up to 5 gpm (20 L/min) and can handle switching frequencies as high as 15,000 cycles per hour, making it suitable for high-demand operations requiring rapid response times of approximately 50 ms.

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.
