The Sun Hydraulics DNDCXTV72419 (DNDCXTV72419) is a robust direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency fluid control in hydraulic systems. This valve is spring-centered to maintain a neutral position and offers precise flow management by redirecting flow paths when either coil A or coil B is energized. Specifically, energizing coil A directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is rated for fatigue resistance at pressures up to 5000 psi (350 bar), ensuring durability under demanding conditions. This valve does not require a minimum hydraulic pressure for operation, making it versatile for various applications. It features a wet armature design, allowing the working fluid to cool the armature but necessitating caution with fluids that may degrade under heat over time. The DNDCXTV72419 can accommodate differential flow circuits by directing higher return flows through specific ports. It also supports EPDM seals suitable for phosphate ester fluids, though these are incompatible with petroleum-based substances. A notable feature of this valve is its high-efficiency solenoid design that provides significant spool actuating force per watt consumed, promoting reliable shifting performance. The product offers interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction. Additionally, it includes options for coil connectors rated up to IP69K for enhanced environmental protection. With a capacity of handling flows up to 5 gpm (20 L/min) and featuring a quick response time of approximately 50 ms, this valve suits applications requiring frequent switching cycles up to 15,000 cycles per hour. Its construction minimizes internal binding risks due to installation torque variations or cavity machining discrepancies.

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.
