The Sun Hydraulics DNDCXTN71219 (DNDCXTN71219) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for various hydraulic applications. This valve is spring-centered to a neutral position and offers versatile flow control based on coil activation. When coil A is energized, the flow path is from port 3 P to port 2 A and from port 4 B to port 1 T; energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The valve boasts a fatigue-rated solenoid tube assembly capable of withstanding service pressures up to 5000 psi (350 bar), ensuring robust performance in demanding environments. It operates without requiring minimum hydraulic pressure, which enhances its usability in differential flow circuits where higher return flows are directed through specific ports. The DNDCXTN71219 features a wet armature design that allows the working fluid to surround the armature, impacting heat dissipation when coils are energized for extended periods. Users should be cautious with fluid selection as certain mixtures may degrade under these conditions. The valve accommodates a variety of coil termination and voltage options, including those with surge protection, contributing to its adaptability in different setups. Its high-efficiency solenoid design delivers significant spool actuating force per wattage used, ensuring reliable shifting performance. Interchangeable coils with other Sun Series 1 solenoid products add flexibility in installation direction and configuration. Connector options provide protection ratings up to IP69K for enhanced environmental resilience. Additionally, the floating style construction minimizes risks of internal binding due to installation torque variations or machining discrepancies. Ideal for systems using phosphate ester fluids when equipped with EPDM seals, this valve supports a capacity of up to 5 gpm (20 L/min) and exhibits low leakage rates at specified viscosities and pressures.

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.
