The Sun Hydraulics DNDCXBV212 (Material Number: DNDCXBV212) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This versatile valve allows for precise control of hydraulic flow, with coil A energization directing flow from port 3 P to port 2 A and from port 4 B to port 1 T, while coil B energization routes flow from port 3 to port 4 and from port 2 to port 1. It is designed for high-pressure applications with a fatigue rating of up to 5000 psi (350 bar), making it suitable for demanding environments. The valve requires no minimum hydraulic pressure for operation due to its direct actuation mechanism. The DNDCXBV212 is particularly effective in differential flow circuits, where higher return flows should be managed through specific ports for optimal performance. It features EPDM seals compatible with phosphate ester fluids, although caution is advised against exposure to petroleum-based products which can damage the seals. The wet armature design ensures that the working fluid mitigates the heat generated by prolonged coil energization, though users should note potential degradation in water-glycol mixtures over time. This model offers numerous coil termination and voltage options, including surge protection capabilities. Coils are interchangeable within Sun's Series 1 solenoid products and can be mounted bi-directionally on the tube. With IP69K-rated connectors available, this valve provides robust environmental protection options. Its floating style construction minimizes binding risks due to installation torque or cavity machining variations. Additional specifications include a capacity of 5 gpm (20 L/min), typical response time of 50 ms, maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), and a switching frequency of up to 15,000 cycles per hour. The valve installs with a torque between 30-35 lbf ft (41-47 Nm) using Viton seal kits for both cartridge and coil components.

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.
