The Sun Hydraulics DNDCXCNHN24AB (DNDCXCNHN24AB) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed to provide precise hydraulic control. This valve features a spring-centered neutral position and operates with no minimum hydraulic pressure requirement. When coil A is energized, hydraulic 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 flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This valve incorporates a wet armature design where the working fluid surrounds the armature, which can affect fluid integrity over time due to heat exposure, particularly in water-glycol mixtures. The DNDCXCNHN24AB offers flexible coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. The high-efficiency solenoid design delivers robust spool actuation force per watt expended, promoting reliable valve shifting. The valve's construction minimizes internal part binding risks due to excessive installation torque or machining variations. It has a capacity of up to 5 gpm (20 L/min) and supports a maximum operating pressure of 5000 psi (350 bar). The typical response time is approximately 50 ms, with maximum leakage at specified conditions being limited to 10 in\u00b3/min (160 cc/min). Suitable for differential flow circuits, this valve directs higher return flows through specific ports for optimal performance. Available seal kits include Viton options for both cartridge and coil applications. With a switching frequency of up to 15,000 cycles per hour and various environmental protection ratings available for coil connectors, the DNDCXCNHN24AB ensures reliable performance across diverse applications requiring precise hydraulic control solutions.

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.
