The Sun Hydraulics DNDCXAV212 (DNDCXAV212) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control. This valve is spring-centered to the neutral position and allows for directional flow changes when solenoids are energized. When coil A is activated, the flow shifts 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. Engineered for high performance, this valve features a fatigue-rated solenoid tube assembly capable of withstanding service pressures up to 5000 psi (350 bar). Notably, it operates without requiring a minimum hydraulic pressure. Designed with versatility in mind, the DNDCXAV212 incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals should not be exposed to petroleum-based products. The wet armature design enhances efficiency but requires consideration in applications involving long coil activation periods due to potential fluid breakdown at elevated temperatures. The valve's high-efficiency solenoid design ensures robust spool actuation with minimal power consumption. The DNDCXAV212 offers various coil termination and voltage options, including configurations with surge protection. Coils are interchangeable within Sun\u2019s Series 1 solenoid products and can be mounted bi-directionally on the tube. With options for IP69K-rated connectors and additional weatherized kits available, this valve accommodates diverse environmental conditions. Its floating style construction minimizes internal binding risks caused by installation torque or machining variations. Key specifications include a capacity of 5 gpm (20 L/min), typical response time of 50 ms, maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), and a switching frequency of up to 15,000 cycles per hour. The valve is compatible with Viton seal kits for both cartridge and coil assemblies.

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.
