The Sun Hydraulics DNDCXAN211 (DNDCXAN211) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to maintain a neutral position. When coil A is energized, fluid flow is directed from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B channels flow from port 3 to port 4 and from port 2 to port 1. This valve operates efficiently under a maximum pressure of 5000 psi (350 bar) without requiring any minimum hydraulic pressure due to its direct actuation design. It features a fatigue-rated solenoid tube assembly for robust service. The DNDCXAN211 utilizes a wet armature design where the working fluid surrounds the armature, which can be affected by heat generated during prolonged coil energization. This aspect is particularly relevant for fluids like water-glycol mixtures that may degrade over time, impacting valve performance. The valve supports various coil termination and voltage options with or without surge protection, offering flexibility in configuration. This model incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. The valve demonstrates high efficiency through its unique magnetic solenoid design that ensures reliable shifting by providing substantial spool actuating force per watt expended. It accommodates interchangeable coils with other Sun Series 1 products and offers coil connector options rated up to IP69K for enhanced environmental protection. With a capacity of handling up to 5 gpm (20 L/min), the valve features a typical response time of approximately 50 ms and can operate at switching frequencies up to 15,000 cycles per hour. The maximum leakage rate at specified conditions is minimal at about 10 in\u00b3/min (160 cc/min). The DNDCXAN211 also includes Viton seal kits for both cartridge and coil components for effective sealing solutions.

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.
