The Sun Hydraulics DNDCXAE812 (Material Number: DNDCXAE812) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for reliable hydraulic control. This valve is spring-centered to the neutral position and features a unique wet armature design that allows the working fluid to surround the armature, which can influence performance during prolonged coil energization due to heat exposure. With no minimum hydraulic pressure required for operation, it offers versatile functionality in differential flow circuits by directing higher return flow through specified ports. The valve is fatigue-rated for service pressures up to 5000 psi (350 bar) and demonstrates a typical response time of 50 milliseconds. It incorporates Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations. The DNDCXAE812 supports a variety of coil termination and voltage options, including those with surge protection capabilities, enhancing its adaptability across different applications. Coils are interchangeable within the Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve's solenoid boasts high efficiency with substantial spool actuating force per watt expended, ensuring dependable valve shifting performance. It also offers coil connector options rated up to IP69K for enhanced environmental protection. With a capacity of 5 gpm (20 L/min) and maximum valve leakage at 10 in\u00b3/min (3000 psi), this valve is suitable for high-frequency switching applications up to 15,000 cycles per hour. It fits into cavity T31A with a series designation of 1 and requires an installation torque between 30-35 lbf ft (41-47 Nm). For systems using phosphate ester fluids, cartridges with EPDM seals are recommended due to their resistance against petroleum-based fluids that could damage standard seals.

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.
