The Sun Hydraulics DNDCXWE212 (DNDCXWE212) is a high-performance, direct acting, solenoid-operated 4-way, 3-position spool valve designed for precise fluid control in hydraulic systems. This valve is spring-centered to the neutral position and allows directional flow control based on coil activation. When coil A is energized, fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. The valve operates efficiently under a maximum pressure of 5000 psi (350 bar) and requires no minimum hydraulic pressure for activation, making it highly versatile in various applications. The DNDCXWE212 features a fatigue-rated solenoid tube assembly and incorporates a wet armature design, which enhances durability by allowing the working fluid to cool the armature. However, users should be cautious with fluids like water-glycol mixtures that may degrade at high temperatures over time. The valve's design includes EPDM seals suited for phosphate ester fluids; exposure to petroleum-based substances can damage these seals. With a capacity of up to 5 gpm (20 L/min), this valve supports high switching frequencies up to 15,000 cycles per hour and offers a typical response time of just 50 milliseconds. The solenoid's magnetic design ensures high efficiency with significant spool actuating force per watt expended. Additionally, interchangeable coils compatible with other Sun Series 1 solenoid products provide flexibility in installation and configuration options. The DNDCXWE212 also incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It offers various coil termination and voltage options with IP69K-rated connectors for enhanced environmental protection. This robust valve is ideal for applications requiring reliable directional control 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.
