The Sun Hydraulics DNDCXTN724N (DNDCXTN724N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This versatile valve efficiently manages fluid flow with its innovative design. When coil A is energized, the flow routes 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 valve's solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. The DNDCXTN724N requires no minimum hydraulic pressure for operation due to its direct actuation mechanism. It features a wet armature design where the working fluid surrounds the armature, which can impact performance if the coil remains energized for extended periods. This feature demands attention when using fluids like water-glycol mixtures that may degrade under heat exposure over time. A wide range of coil termination and voltage options are available, with or without surge protection, ensuring compatibility with various systems. Coils are interchangeable with other Sun Series 1 solenoid products and offer mounting flexibility in either direction. The valve incorporates Sun's floating style construction, minimizing potential internal binding issues due to installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min) and a typical response time of just 50 ms, this valve supports high-frequency switching up to 15,000 cycles per hour. The DNDCXTN724N is designed for robust performance with maximum valve leakage at specified conditions limited to just 10 in\u00b3/min (160 cc/min). Additionally, it offers various seal options compatible with different fluid types while maintaining environmental protection standards up to IP69K through available coil connector options.

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.
