The Sun Hydraulics DNDCXWV211 (DNDCXWV211) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise flow control in hydraulic systems. This valve is spring-centered to a neutral position and operates by energizing one of the two coils. When coil A is activated, the flow path directs 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. The valve is fatigue rated for service up to 5000 psi (350 bar) and requires no minimum hydraulic pressure for operation, making it versatile for various applications. The DNDCXWV211 features a wet armature design that allows working fluid exposure around the armature, which can be crucial for thermal management during prolonged coil activation. It also incorporates Sun's unique floating style construction to prevent internal binding due to installation torque or machining variations. The solenoid boasts high efficiency with significant spool actuating force per watt expended, ensuring reliable operation. This model supports differential flow circuits by directing higher return flows through specific ports and offers numerous coil termination and voltage options with surge protection capabilities. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. For enhanced environmental protection, weatherized coils and kits are available. The valve fits into cavity T-31A with a capacity of up to 5 gpm (20 L/min) and exhibits a typical response time of approximately 50 ms. It maintains a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar) and supports switching frequencies up to 15,000 cycles per hour. The solenoid tube has a diameter of .75 inches (19 mm), while the valve hex size measures .78 inches (22.2 mm). Installation torque ranges between 30-35 lbf ft (41-47 Nm), ensuring secure placement in 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.
