The Sun Hydraulics DNDCXRE212 (DNDCXRE212) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient fluid control. This model is spring-centered to maintain a neutral position when not energized. Upon energizing coil A, the valve 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 constructed to withstand fatigue at service pressures up to 5000 psi (350 bar). This valve functions without requiring a minimum hydraulic pressure, making it versatile for various applications. In differential flow circuits, it is recommended that higher return flows be directed through port 2 A to port 1 T. The valve features EPDM seals specifically suited for systems utilizing phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Its wet armature design allows the working fluid to cool the armature but requires caution with certain fluids like water-glycol mixtures that may degrade over time due to heat exposure. The DNDCXRE212 offers various coil termination and voltage options, including configurations with surge protection for enhanced versatility. Its high-efficiency solenoid design ensures reliable valve shifting by providing substantial spool actuating force per watt of power used. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, coil connector options are available with ratings up to IP69K for superior environmental protection. This model incorporates Sun's floating style construction method, minimizing internal part binding risks due to installation torque or machining variations in cavity or cartridge settings. With a capacity of handling flows up to 5 gpm (20 L/min) and a swift response time of approximately 50 ms, this valve is engineered for high performance and durability in demanding hydraulic systems.

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.
