The Sun Hydraulics DNDATYV912 (DNDATYV912) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability in high-pressure applications. It functions without any minimum hydraulic pressure requirement, making it versatile for various systems. The cartridge offers multiple manual override options, although these are not compatible with weatherized coils. For models with D or L control, the detent mechanism is intended for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. It's important to note that cartridges with EPDM seals should only be used with phosphate ester fluids to prevent seal damage from petroleum-based substances. This valve employs a wet armature design that allows the working fluid to surround the armature, which can be beneficial or detrimental depending on fluid type and operation duration due to heat exposure from the coil. A variety of coil termination and voltage configurations are available, including options with surge protection. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt used, ensuring reliable shifting. The DNDATYV912 fits into a T31A cavity and belongs to Series 1 with a capacity of 10 gpm (40 L/min). It supports up to 5000 psi (350 bar) maximum operating pressure and typically responds within 50 milliseconds. The valve has minimal leakage at standard conditions and can handle switching frequencies up to 15,000 cycles per hour. Its construction minimizes internal binding risks due to installation torque or machining variations. Interchangeable coils compatible with other Sun Series 1 products further enhance its adaptability in diverse environments.

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.
