The Sun Hydraulics DNCADTV712N (DNCADTV712N) is a high-performance, solenoid-operated directional valve, known for its robust and efficient control in hydraulic systems. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool with closed transitions that minimize oil loss during position shifts, making it particularly effective in pilot control circuits. The valve operates with an impressive capacity of 8 gpm/30 L/min and can handle a maximum operating pressure of 5000 psi/350 bar. Designed for versatility, the DNCADTV712N has a variety of coil termination and voltage options available, which can be tailored to include surge protection depending on the application needs. Its solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and reliability even under strenuous conditions. Additionally, the valve incorporates Sun's floating style construction which reduces the risk of internal parts binding due to installation variances or cavity/cartridge machining errors. The wet armature design utilized by this model means that the working fluid surrounds the armature; this is an important consideration as prolonged energization of the coil could affect fluid integrity in certain applications. Users should note that cartridges configured with EPDM seals are specifically designed for phosphate ester fluids and should not be exposed to petroleum-based substances which could damage these seals. Furthermore, this model's quick response time (typically 50 ms), combined with its ability to switch up to 15,000 cycles per hour, makes it highly suitable for applications requiring rapid and frequent operations. The manual override feature requires minimal force and offers precision control over valve operation. For those seeking a reliable solution in directional control applications within hydraulic systems, the Sun Hydraulics DNCADTV712N offers a compelling blend of performance and flexibility.

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.
