The Sun Hydraulics DNDATDV912N (DNDATDV912N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar), ensuring robust performance in demanding hydraulic applications. This valve does not require minimum hydraulic pressure to operate and offers various manual override options, although manual overrides are incompatible with weatherized coils. Notably, models with D or L control include a detent mechanism intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve is suitable for systems using phosphate ester fluids when equipped with EPDM seals but should avoid petroleum-based fluids due to potential seal damage. The DNDATDV912N employs a wet armature design, where the working fluid surrounds the armature, exposing it to heat from the coil\u2014important for applications involving long coil energization periods. High-efficiency solenoids provide substantial spool actuating force per Watt, enhancing reliable valve shifting. The cartridge accommodates various coil termination and voltage options, including those with surge protection and IP69K-rated connectors for environmental resilience. This model incorporates Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1, offering a flow capacity of up to 10 gpm (40 L/min) and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). With a typical response time of 50 ms and switching frequency capability of up to 15,000 cycles/hr, this valve is engineered for high-performance applications requiring precise directional control under rigorous conditions.

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.
