The Sun Hydraulics DNDCXRE948 (DNDCXRE948) 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 efficient fluid control in hydraulic systems, with flow configurations determined by energizing either coil A or coil B. 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, activating coil B directs the 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 up to a maximum operating pressure of 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The DNDCXRE948 valve operates without requiring a minimum hydraulic pressure due to its direct actuation design, making it suitable for various applications where immediate response times are critical. Its wet armature design allows the working fluid to cool the armature but requires consideration of fluid types as certain mixtures may degrade over time with heat exposure. The valve supports differential flow circuits by directing higher return flows through specific ports. A wide range of coil termination and voltage options are available for this model, including configurations with surge protection and weatherized coils for enhanced environmental resistance. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt expended. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Incorporating Sun's floating style construction minimizes internal binding risks due to installation torque or machining variations. The DNDCXRE948 has a capacity of up to 5 gpm (20 L/min) and features a quick typical response time of approximately 50 ms, with a switching frequency capability of up to 15,000 cycles per hour.

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.
