The Sun Hydraulics DNDCXBE212 (DNDCXBE212) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency hydraulic systems. It features a spring-centered neutral position and allows for controlled flow direction based on coil energization: energizing coil A directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while coil B directs flow from port 3 to port 4 and from port 2 to port 1. This valve is rated for fatigue at service pressures up to 5000 psi (350 bar), making it robust for demanding applications. It operates without the need for minimum hydraulic pressure, suitable for differential flow circuits where higher return flows are directed through specific ports. The valve incorporates EPDM seals compatible with phosphate ester fluids but requires caution against exposure to petroleum-based substances. Utilizing a wet armature design, it efficiently manages heat dissipation but necessitates consideration of fluid compatibility due to potential varnish formation at elevated temperatures. The solenoid's magnetic design enhances operational efficiency, ensuring reliable spool actuation with minimal energy consumption. It offers diverse coil termination and voltage options, including surge protection, and supports interchangeability with other Sun Series 1 solenoid products. Coil connectors are available with ratings up to IP69K for enhanced environmental protection. The valve's construction minimizes internal binding risks due to installation torque variations or machining discrepancies in cavities or cartridges. With a capacity of handling flows up to 5 gpm (20 L/min) and a typical response time of 50 ms, this product is engineered for high-frequency switching applications 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.
