The Sun Hydraulics DNCADTV712 (DNCADTV712) is a high-performance, solenoid-operated directional valve that offers precision control in hydraulic systems. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool with a closed transition, which minimizes oil loss during position shifts and is particularly useful in pilot control circuits. The valve is designed to handle a flow capacity of 8 gpm (30 L/min) with maximum operating pressures up to 5000 psi (350 bar), making it robust for demanding applications. Notably, the DNCADTV712 operates effectively without any minimum hydraulic pressure requirement and incorporates a wet armature design. This design allows the working fluid to surround the armature, which can be beneficial or detrimental depending on the duration the coil is energized and the type of fluid used. The valve is also configured with EPDM seals suitable for phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage these seals. The versatility of the DNCADTV712 extends to its coil options, which are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. These coils come in various termination and voltage configurations, potentially including surge protection, and are designed for high efficiency with superior spool actuating force per watt expended. Additional features like IP69K rated connector options and weatherized coils enhance its adaptability to different environmental conditions. Furthermore, this model benefits from Sun\u2019s floating style construction which reduces risks associated with internal parts binding due to installation torque or cavity/cartridge machining variations. With a rapid response time of approximately 50 ms and capable of handling up to 15,000 switching cycles per hour, the DNCADTV712 provides reliable performance for advanced hydraulic system applications.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- 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.
- Cartridges configured 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.
