The Sun Hydraulics DNDCXHV548 (DNDCXHV548) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency performance in hydraulic systems. It features a spring-centered neutral position and offers versatile flow control: energizing coil A directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. This valve is engineered for robust operation with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). It does not require minimum hydraulic pressure for activation, making it suitable for various applications. The valve's construction includes a wet armature design that allows working fluid exposure to coil-generated heat. This feature can impact long-term function in systems using fluids like water-glycol mixtures due to potential varnish formation. The DNDCXHV548 supports various coil termination and voltage options, with interchangeable coils that fit other Sun Series 1 solenoid products. Coil connectors are available with ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction, reducing the risk of internal part binding due to installation torque or machining variations. It operates within a capacity of 5 gpm (20 L/min) and provides a typical response time of 50 ms. With a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this valve ensures efficient performance across high-frequency operations up to 15,000 cycles per hour. The DNDCXHV548 is equipped with Viton seal kits (990431006 for the cartridge and Viton: 990770006 for the coil) ensuring compatibility with specific fluid types while maintaining durability under demanding conditions.

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.
