The Sun Hydraulics DNDCXAN228 (DNDCXAN228) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This valve features a robust solenoid tube assembly rated for fatigue service at 5000 psi (350 bar), ensuring high reliability in demanding applications. It operates without requiring minimum hydraulic pressure, making it suitable for various hydraulic systems. The valve's design allows for differential flow circuits where higher return flow should be directed from port 2 A to port 1 T. It is important to note that cartridges with EPDM seals are intended for use with phosphate ester fluids and should not be exposed to petroleum-based products. This valve employs a wet armature design, which means the working fluid surrounds the armature and absorbs heat generated by the coil. Users should consider this factor when the coil is energized for extended periods, as certain fluids may degrade and affect performance over time. The DNDCXAN228 offers versatility with a wide range of coil termination and voltage options, including configurations with surge protection. The solenoid's unique magnetic design enhances efficiency by delivering high spool actuating force per watt expended, ensuring reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options provide ratings up to IP69K for enhanced environmental protection. Additionally, weatherized coils and kits are available for complete protection against harsh conditions. The valve incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or cavity/cartridge machining variations. With a capacity of 5 gpm (20 L/min), response time of approximately 50 ms, and switching frequency of up to 15,000 cycles per hour, this versatile spool valve is designed for efficient performance in various hydraulic applications.

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.
