The Sun Hydraulics DNDCXRN928 (DNDCXRN928) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This versatile valve allows for precise flow control in hydraulic systems. When coil A is energized, the flow transitions 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. Designed for robustness, the solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar). This valve does not require a minimum hydraulic pressure for operation, making it suitable for various applications. In differential flow circuits, directing higher return flows through port 2 A to port 1 T optimizes performance. The valve is equipped with EPDM seals compatible with phosphate ester fluids but should not be exposed to petroleum-based substances as they may cause damage. The wet armature design enhances efficiency but necessitates caution with certain fluids like water-glycol mixtures due to potential breakdown at high temperatures. The DNDCXRN928 offers numerous coil termination and voltage options with or without surge protection and features a unique magnetic design that ensures high spool actuating force per watt expended. Coils are interchangeable among Sun Series 1 solenoid products and can be mounted in either direction on the tube. With coil connector options rated up to IP69K and additional weatherized coils available, this valve provides comprehensive environmental protection. Incorporating Sun's floating style construction minimizes internal binding risks due to installation torque or machining variations. It fits into cavity T31A and supports a capacity of up to 5 gpm (20 L/min). The valve has a typical response time of around 50 ms and can handle switching frequencies up to 15,000 cycles per hour while maintaining low 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.
