The Sun Hydraulics DNDCXYE812 (DNDCXYE812) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic flow control. It features a spring-centered neutral position and offers distinct flow paths depending on which coil is energized. When coil A is activated, the flow transitions from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs the flow from port 3 to port 4 and from port 2 to port 1. This valve is engineered for high-performance applications with its solenoid tube assembly fatigue rated for up to 5000 psi (350 bar), ensuring robust service life. Notably, the valve requires no minimum hydraulic pressure for operation due to its direct actuation design. It incorporates a wet armature design, which means the working fluid surrounds the armature and absorbs heat generated by the coil\u2014a crucial consideration when operating continuously at elevated temperatures. The valve's high-efficiency solenoid provides significant spool actuating force per watt consumed, ensuring reliable operation even under demanding conditions. This model supports various coil terminations and voltage options, including configurations with surge protection. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. The valve also boasts an IP69K rating for certain coil connector options, offering excellent environmental protection. Sun Hydraulics' floating style construction minimizes the risk of internal part binding due to excessive installation torque or machining variations in cavity or cartridge fabrication. With a capacity of up to 5 gpm (20 L/min) and a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this versatile valve is suitable for various industrial applications requiring reliable directional control of hydraulic fluids.

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.
