The Sun Hydraulics DNDCXHV628 (DNDCXHV628) is a robust direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control applications. This valve is spring-centered to the neutral position and features a high-efficiency solenoid with a unique magnetic design that ensures reliable valve shifting with high spool actuating force per watt expended. When coil A is energized, the flow direction is 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. The solenoid tube assembly is rated for fatigue at up to 5000 psi (350 bar), ensuring durability and longevity in demanding environments. This valve does not require minimum hydraulic pressure for operation, making it ideal for various applications where direct actuation is necessary. It incorporates a wet armature design allowing the working fluid to surround the armature, which helps dissipate heat generated by the coil but may affect certain fluids over time due to heat exposure. The DNDCXHV628 offers versatility in coil termination and voltage options, with some configurations providing surge protection and IP69K ratings for enhanced environmental protection. Installation of this valve is straightforward due to its floating style construction which minimizes potential internal part binding caused by excessive installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min), this valve meets various flow requirements while maintaining low leakage rates at maximum operating pressures. Additionally, it supports high switching frequencies up to 15,000 cycles per hour, making it suitable for dynamic systems requiring rapid response times typically around 50 ms. The use of EPDM seals allows compatibility with phosphate ester fluids; however, exposure to petroleum-based substances should be avoided as they can damage the seals.

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.
