The Sun Hydraulics DNDCXBV211 (Material Number: DNDCXBV211) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency hydraulic systems. This valve is spring-centered to the neutral position and offers precise control over fluid flow. When coil A is energized, the flow transitions from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects the flow from port 3 to port 4 and from port 2 to port 1. Built for durability, the solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring reliable performance under demanding conditions. The DNDCXBV211 operates without requiring minimum hydraulic pressure due to its direct actuation design. For differential flow circuits, it is recommended that higher return flows be directed through port 2 A to port 1 T. The valve features a wet armature design, where working fluid surrounds the armature and absorbs heat generated by the coil. Users should note that certain fluids, like water-glycol mixtures, may degrade under prolonged exposure to these temperatures. This model provides various coil termination and voltage options with or without surge protection and features interchangeable coils compatible with other Sun Series 1 solenoid products. With a unique magnetic design yielding high spool actuating force per watt expended, this valve ensures dependable shifting capabilities. The valve's construction incorporates Sun's floating style design, minimizing internal binding risks due to installation torque or machining variations. Additional specifications include a capacity of up to 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/hr. The DNDCXBV211 supports robust applications with its IP69K-rated coil connector options for enhanced environmental protection.

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.
