The Sun Hydraulics DNDCXBV (DNDCXBV) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for versatility and reliability in hydraulic systems. It features a spring-centered neutral position, allowing precise control over hydraulic flow paths. 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 directs the flow from port 3 to port 4 and from port 2 to port 1. This valve is engineered for high performance with a solenoid tube assembly fatigue rated for up to 5000 psi (350 bar), ensuring durability under demanding conditions. The DNDCXBV does not require minimum hydraulic pressure for operation due to its direct actuation design. It is particularly suitable for differential flow circuits where higher return flows should be routed through specific ports. The valve uses a wet armature design, which immerses the armature in the working fluid, exposing it to heat generated by the coil\u2014a factor to consider with fluids prone to breakdown at elevated temperatures. A variety of coil termination and voltage options are available, including configurations with surge protection. The solenoid's magnetic design ensures high efficiency with substantial spool actuating force per watt expended. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction. The valve's construction minimizes internal binding risks due to excessive installation torque or machining variations. Specifications include a cavity size of T31A, a capacity of up to 5 gpm (20 L/min), and a maximum operating pressure of 5000 psi (350 bar). It offers rapid response times typically around 50 ms and supports switching frequencies up to 15,000 cycles per hour. Seal kits are available in Viton material for both cartridge and coil applications ensuring compatibility with various hydraulic fluids.

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.
