The Sun Hydraulics DNDCXYN712 (DNDCXYN712) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control applications. This valve features a spring-centered neutral position and offers versatile flow configurations depending on which coil is energized. When coil A is activated, fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for robust performance with a fatigue rating suitable for up to 5000 psi (350 bar) service. The DNDCXYN712 does not require a minimum hydraulic pressure for operation, making it adaptable for various system requirements. It incorporates a wet armature design that allows the working fluid to surround the armature, providing cooling but also necessitating consideration of fluid compatibility due to potential heat exposure. Specifically, EPDM seals are recommended when used with phosphate ester fluids; petroleum-based fluids should be avoided as they can damage these seals. This valve supports a range of coil termination and voltage options, some with surge protection features, ensuring flexibility in installation and application. The high-efficiency solenoid design delivers substantial spool actuating force per watt, ensuring reliable valve operation across diverse conditions. With interchangeable coils compatible with other Sun Series 1 solenoid products, the DNDCXYN712 offers ease of maintenance and versatility in component replacement. Additional technical specifications include a capacity of up to 5 gpm (20 L/min), maximum valve leakage at specified conditions of up to 10 in\u00b3/min (3000 psi), and compatibility with cavity T-31A Series 1 installations. The valve's construction minimizes potential binding issues during installation due to excessive torque or machining variations.

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.
