The Sun Hydraulics DNDCXWV714 (DNDCXWV714) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precision flow control in hydraulic systems. This valve is spring-centered to the neutral position and offers two operational modes depending on coil activation. When coil A is energized, fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for high endurance, supporting service pressures up to 5000 psi (350 bar), making it suitable for demanding applications. This valve operates without the need for a minimum hydraulic pressure due to its direct actuation design. It features a wet armature design that allows the working fluid to surround the armature, which can be crucial in applications where continuous energizing of the coil occurs. Users should be mindful of fluid compatibility; specifically, EPDM seals are intended for phosphate ester fluids and can degrade when exposed to petroleum-based substances. The DNDCXWV714 offers versatility with various coil termination and voltage options available, including configurations with surge protection. Its high-efficiency solenoid design ensures reliable shifting with significant spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and offer IP69K-rated connector options for enhanced environmental protection. Built using Sun's floating style construction, this valve minimizes internal part binding due to installation torque or machining variations. With a capacity of 5 gpm (20 L/min) and response time typically at 50 ms, it supports a switching frequency of up to 15,000 cycles/hr. The valve's robust construction makes it ideal for applications requiring quick response and high reliability under challenging conditions.

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.
