The Sun Hydraulics DNDCXHN914N (DNDCXHN914N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control. This valve is spring-centered to a neutral position and can be actuated by energizing either coil A or coil B. When coil A is energized, fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly of this valve is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring robust performance in demanding applications. This valve operates without the need for minimum hydraulic pressure, making it suitable for various hydraulic systems. It features a wet armature design, where the working fluid surrounds the armature, which helps dissipate heat generated by the coil but may affect certain fluids like water-glycol mixtures over time. The DNDCXHN914N offers multiple coil termination and voltage options with surge protection available, enhancing its versatility in different setups. The high-efficiency solenoid design provides significant spool actuating force per watt expended, promoting reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be installed in either direction on the tube. For environmental resilience, coil connector options are rated up to IP69K with additional weatherized coils and kits available. Engineered with Sun's floating style construction, this valve minimizes internal part binding risks due to installation torque or cavity machining variations. It fits into a T31A cavity and has a capacity of handling flow rates up to 5 gpm (20 L/min). The typical response time is around 50 ms with a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). This product supports switching frequencies up to 15,000 cycles per hour, making it a reliable choice for rapid cycling 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.
