The Sun Hydraulics DNDCXTV71299 (DNDCXTV71299) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precision fluid control. This valve is spring-centered to the neutral position, providing reliable operation in hydraulic systems. Upon energizing coil A, the flow is directed from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects the flow from port 3 to port 4 and from port 2 to port 1. Built with a solenoid tube assembly rated for fatigue at pressures up to 5000 psi (350 bar), this valve requires no minimum hydraulic pressure for activation, making it versatile for various applications. The DNDCXTV71299 features a wet armature design where the working fluid envelops the armature, potentially affecting performance if exposed to high temperatures over prolonged periods. Notably, fluids like water-glycol mixtures may degrade under such conditions. The valve offers a range of coil termination and voltage configurations with surge protection options available. Its high-efficiency solenoid design ensures substantial spool actuating force per watt, enhancing shifting reliability. Compatible with Sun Series 1 solenoid products, the coils can be mounted in any direction and are interchangeable. Connector options provide protection ratings up to IP69K for enhanced durability in harsh environments. The valve's construction minimizes internal binding risks due to over-torque or machining inconsistencies. With a capacity of up to 5 gpm (20 L/min), the DNDCXTV71299 supports a maximum operating pressure of 5000 psi (350 bar) and exhibits typical response times of around 50 ms. It allows switching frequencies up to 15,000 cycles per hour with minimal leakage at specified viscosities. The valve uses Viton seals available in specific kits for both cartridge and coil components, ensuring compatibility with various system requirements.

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.
