The Sun Hydraulics DNDCXANHN24AA (DNDCXANHN24AA) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This high-performance valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and features a fatigue-rated solenoid tube assembly. The valve efficiently directs hydraulic flow between ports based on coil energization: with coil A energized, flow moves from port 3 P to port 2 A and from port 4 B to port 1 T; with coil B energized, flow shifts from port 3 to port 4 and from port 2 to port 1. It requires no minimum hydraulic pressure for operation, making it highly versatile in various applications. The DNDCXANHN24AA incorporates a wet armature design that allows working fluid to surround the armature, which can be crucial for temperature-sensitive applications. The valve supports differential flow circuits by directing higher return flows through specific ports. It is compatible with EPDM seals for systems utilizing phosphate ester fluids but should avoid petroleum-based fluids due to potential seal damage. This model offers various coil termination and voltage options, including those with surge protection, ensuring adaptability across different systems. Its unique magnetic design ensures high efficiency by providing substantial spool actuating force per watt expended. The coils are interchangeable within the Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environmental resilience, the valve offers coil connector options rated up to IP69K. With a capacity of up to 5 gpm (20 L/min), this valve is ideal for systems demanding reliable performance and minimal internal binding risks due to its floating style construction. The DNDCXANHN24AA provides quick response times typically around 50 ms and supports a switching frequency of up to 15,000 cycles per hour.

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.
