The Sun Hydraulics DNDCXWN72499 (DNDCXWN72499) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This valve is designed for high-efficiency applications and does not require a minimum hydraulic pressure for operation. When coil A is activated, the flow transitions 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. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring robust performance under demanding conditions. The DNDCXWN72499 model incorporates a wet armature design where the working fluid surrounds the armature, allowing exposure to coil-generated heat. This design consideration is crucial as certain fluids may degrade at elevated temperatures over time, potentially affecting valve functionality. The valve supports various coil termination and voltage options, with some configurations offering surge protection for enhanced reliability. Notably, this valve employs Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. Its solenoid's unique magnetic design ensures high efficiency by delivering significant spool actuating force per watt consumed. Coil interchangeability with other Sun Series 1 solenoid products adds flexibility in application setups. For users requiring environmental resilience, coil connector options provide ratings up to IP69K, with additional weatherized coils and kits available for comprehensive protection. The valve's cavity designation is T31A with a capacity of up to 5 gpm (20 L/min). It exhibits a typical response time of approximately 50 ms and can sustain switching frequencies up to 15,000 cycles per hour. Maximum allowable leakage at specified conditions is limited to ensure optimal performance across diverse hydraulic systems.

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.
