The Sun Hydraulics DNDCXHN648 (DNDCXHN648) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This versatile valve is designed for hydraulic systems requiring precise control of fluid flow. When coil A is energized, it directs flow from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B channels flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly can withstand pressures up to 5000 psi (350 bar), making it suitable for high-pressure applications. This valve operates without the need for minimum hydraulic pressure and features a wet armature design that enhances efficiency by using the working fluid as a coolant for the armature. However, users should be cautious of prolonged coil energization as certain fluids may degrade over time under heat exposure. The DNDCXHN648 offers flexibility with various coil termination and voltage options, some with surge protection capabilities. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. The valve's design incorporates Sun's floating style construction to reduce internal part binding due to installation torque or machining variations. It has a capacity of up to 5 gpm (20 L/min) and exhibits minimal leakage at maximum operating conditions. Its quick response time of approximately 50 ms ensures efficient operation in dynamic systems, while its switching frequency capability reaches up to 15,000 cycles per hour. For environments requiring additional protection against harsh conditions, weatherized coils and kits are available, with some connector options rated up to IP69K for superior environmental resistance. The DNDCXHN648 is compatible with phosphate ester fluid systems when equipped with EPDM seals but should not be exposed to petroleum-based substances which could compromise seal integrity.

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.
