The Sun Hydraulics DNDCXRN236 (DNDCXRN236) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precision flow control in hydraulic systems. This valve is spring-centered to the neutral position, allowing for versatile operation. 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. The solenoid tube assembly is robustly engineered for fatigue resistance up to a service pressure of 5000 psi (350 bar), ensuring durability in demanding applications. This valve operates without requiring a minimum hydraulic pressure, making it suitable for various system configurations. In differential flow circuits, optimal performance is achieved when higher return flows are routed through port 2 A to port 1 T. It features EPDM seals compatible with phosphate ester fluids; however, these are susceptible to damage when exposed to petroleum-based substances. The wet armature design enhances efficiency by immersing the armature in working fluid, although caution is advised as prolonged coil energization may lead to fluid degradation in certain mixtures. The DNDCXRN236 offers flexibility with multiple coil termination and voltage options, including surge protection capabilities. Its high-efficiency solenoid design delivers superior spool actuating force per watt expended, ensuring reliable operation across various conditions. Coils are compatible with other Sun Series 1 products and can be mounted bidirectionally on the tube. With IP69K-rated coil connector options available, this valve can withstand harsh environmental conditions. Additionally, its floating style construction minimizes internal binding risks due to installation torque or machining variations. The valve fits into cavity T-31A and belongs to Series 1 with a capacity of up to 5 gpm (20 L/min). It exhibits a typical response time of approximately 50 ms and maintains maximum leakage at specified conditions within acceptable limits for precise control applications.

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.
