The Sun Hydraulics DNDCXRN2E12V (Material Number: DNDCXRN2E12V) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This versatile valve is designed for efficient hydraulic flow control. When coil A is energized, it directs flow from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is robustly engineered for fatigue resistance at service pressures up to 5000 psi (350 bar), eliminating the need for minimum hydraulic pressure during operation. The valve's design accommodates differential flow circuits by directing higher return flows through specific ports, optimizing system performance. It features EPDM seals suitable for systems using phosphate ester fluids, although these seals are incompatible with petroleum-based fluids. The wet armature design allows the working fluid to surround the armature, which may impact performance if the coil remains energized for extended periods due to heat exposure. This model offers various coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. The unique magnetic design enhances efficiency by providing high spool actuating force per watt consumed. Coil connector options provide protection ratings up to IP69K, ensuring reliability in harsh environments. With a cavity size of T-31A and a capacity of up to 5 gpm (20 L/min), this valve supports high switching frequency\u2014up to 15,000 cycles per hour\u2014and maintains minimal leakage rates under specified conditions. Its floating style construction reduces internal binding risks due to installation or machining variations. This makes it an excellent choice for applications requiring precise hydraulic control and dependable performance under demanding 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.
