The Sun Hydraulics DNDCXRV712N (DNDCXRV712N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic control. This valve features a spring-centered neutral position and operates with no minimum hydraulic pressure requirement, making it versatile for various applications. When coil A is energized, 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 rated for fatigue service up to 5000 psi (350 bar), ensuring durability under demanding conditions. The valve's wet armature design allows the working fluid to surround the armature, which can impact performance if the coil remains energized for extended periods due to potential fluid breakdown at high temperatures. This makes it crucial in applications where temperature management is essential. The DNDCXRV712N offers multiple coil termination and voltage options, including configurations with surge protection for enhanced reliability. This model incorporates a unique magnetic design that enhances solenoid efficiency by providing high spool actuating force per watt expended, thus ensuring reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional weatherized coils and kits are available for environments requiring complete protection. The valve features Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It has a capacity of up to 5 gpm (20 L/min) and operates with maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The typical response time is approximately 50 ms, supporting switching frequencies up to 15,000 cycles per hour.

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.
