The Sun Hydraulics DNDCXHV72419 (Material Number: DNDCXHV72419) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control applications. This valve is spring-centered to the neutral position, allowing for versatile flow direction based 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 built for durability with a fatigue rating suitable for up to 5000 psi (350 bar) service pressure. This valve operates efficiently without needing a minimum hydraulic pressure, making it adaptable in various hydraulic systems. It features EPDM seals compatible with phosphate ester fluids but unsuitable for petroleum-based substances due to potential seal damage. The wet armature design ensures the working fluid surrounds the armature, which can be affected by prolonged coil energization as some fluids may degrade and form varnishes at high temperatures. The DNDCXHV72419 offers multiple coil termination and voltage configurations, including options with surge protection, ensuring compatibility with diverse system requirements. It employs a high-efficiency solenoid design that provides significant spool actuating force per watt expended, ensuring reliable performance. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. This valve incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min), a typical response time of 50 ms, and a switching frequency of up to 15,000 cycles per hour, this valve is robustly designed for demanding hydraulic applications requiring precise control and reliability.

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.
