The Sun Hydraulics DNDATYV712 (DNDATYV712) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve features a fatigue-rated solenoid tube assembly capable of withstanding up to 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The valve operates without requiring minimum hydraulic pressure and offers several manual override options for flexibility in diverse environments. However, it's important to note that manual override functionality is incompatible with weatherized coils. Designed with a wet armature, the DNDATYV712 ensures efficient heat dissipation from the coil, although users should be cautious when using fluids like water-glycol mixtures that may degrade under prolonged exposure to heat. The solenoid's unique magnetic design provides high efficiency and reliable valve shifting by maximizing spool actuating force per watt of power expended. Compatible with various coil termination and voltage options, including those offering surge protection, this valve can be customized to meet specific operational needs. The cartridge incorporates Sun's floating style construction to reduce the risk of internal parts binding due to installation torque or machining variations. It fits into a T-31A cavity and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The DNDATYV712 has a typical response time of 50 ms and can handle switching frequencies up to 15,000 cycles per hour. With a maximum valve leakage rate at 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar), it ensures efficient performance in hydraulic circuits. For maintenance or replacement purposes, Viton seal kits are available for both the cartridge and coil components. This versatile directional valve is designed for applications requiring precise control and high reliability in hydraulic systems.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- 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.
