The Sun Hydraulics DNDCXBE72499 (DNDCXBE72499) is a direct acting, solenoid-operated, four-way, three-position spool valve designed for efficient flow control in hydraulic systems. This valve features a spring-centered neutral position and operates by energizing coil A to direct flow 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 redirected from port 3 to port 4 and from port 2 to port 1. Engineered for robust performance, the solenoid tube assembly is rated for fatigue at up to 5000 psi (350 bar), ensuring reliable service under demanding conditions without requiring minimum hydraulic pressure for operation. The valve's design incorporates a wet armature system where the working fluid surrounds the armature, which may influence fluid stability if the coil remains energized for extended periods. Notably, fluids such as water-glycol mixtures can degrade at high temperatures, potentially affecting cartridge performance over time. The DNDCXBE72499 offers versatility with various coil termination and voltage options available, including configurations with surge protection. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt used. Installation flexibility is supported by interchangeable coils compatible with other Sun Series 1 solenoid products, allowing mounting in either direction. For added durability in harsh environments, coil connector options are rated up to IP69K, with additional weatherized coils and kits available for comprehensive environmental protection. To prevent internal parts binding due to installation torque or machining variations, this valve employs a floating style construction. With a capacity of 5 gpm (20 L/min) and a rapid response time of approximately 50 ms, this valve ensures precise control across applications requiring frequent switching cycles\u2014up to 15,000 cycles per hour\u2014while maintaining minimal leakage rates under specified conditions.

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.
