The Sun Hydraulics DNDCXYN624N (Material Number: DNDCXYN624N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This valve facilitates fluid flow from port 3 P to port 2 A and from port 4 B to port 1 T when coil A is energized. Conversely, when coil B is energized, the flow redirects from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly of this valve is rated for fatigue at a maximum operating pressure of up to 5000 psi (350 bar), making it suitable for high-pressure applications without requiring minimum hydraulic pressure for operation. The valve design incorporates a wet armature system where the working fluid surrounds the armature, exposing it to heat generated by the coil. Such exposure can affect certain fluids like water-glycol mixtures over time due to heat breakdown, potentially forming varnishes that impair cartridge function. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended; however, exposure to petroleum-based fluids will damage these seals. This model offers high efficiency due to its unique magnetic design, ensuring reliable valve shifting with substantial spool actuating force per watt expended. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also features various coil termination and voltage options available with or without surge protection, providing flexibility in different operational environments. The valve's construction minimizes internal part binding risks due to excessive installation torque or cavity-cartridge machining variations. Additional specifications include a capacity of up to 5 gpm (20 L/min), typical response time of approximately 50 ms, maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), and a switching frequency of up to 15,000 cycles/hr.

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.
