The Sun Hydraulics DNDCXTV828 (DNDCXTV828) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency hydraulic systems. This valve features a spring-centered neutral position and operates by energizing coils to control fluid flow between designated ports. Specifically, when coil A is activated, the flow is directed from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects the flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly of this valve is fatigue rated for service pressures up to 5000 psi (350 bar), ensuring robust performance in demanding applications. The DNDCXTV828 does not require minimum hydraulic pressure for operation due to its direct actuated design. It is particularly suitable for differential flow circuits where higher return flows are routed through specific ports for optimal performance. The valve employs a wet armature design that allows working fluid exposure around the armature, which can be advantageous or detrimental depending on fluid type and operating conditions. This product offers versatility with various coil termination and voltage options, some of which include surge protection. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt consumed. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted bi-directionally on the tube. The valve incorporates Sun\u2019s floating style construction to reduce internal binding risks due to installation torque or machining variations. It fits into a T-31A cavity with a capacity of up to 5 gpm (20 L/min) and has a typical response time of approximately 50 ms. Its maximum leakage rate at specified conditions is minimal at about 10 in\u00b3/min (160 cc/min). Additional features include a high switching frequency capability of up to 15,000 cycles per hour and compatibility with Viton seal kits for enhanced durability in various environments.

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.
