The Sun Hydraulics DNDATZV812N (DNDATZV812N) is a solenoid-operated 4-way, 2-position cartridge valve, designed with a direct-acting, balanced spool for directional control. With a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), this valve operates without the need for minimum hydraulic pressure. It features multiple manual override options, including models with D or L control equipped with a temporary actuation detent mechanism, boasting a mechanical life expectancy of approximately 7,000 cycles. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. The valve employs a wet armature design which may affect the function if exposed to prolonged coil heat, particularly in water-glycol mixtures. A variety of coil terminations and voltage options are available, ensuring high efficiency and reliable shifting due to its unique magnetic design. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction. The valve offers coil connector options up to IP69K rating for enhanced environmental protection. It incorporates Sun's floating style construction minimizing the risk of internal part binding from excessive installation torque or machining variations in the cavity/cartridge. With a cavity size of T-31A and Series 1 capacity of up to 10 gpm (40 L/min), it allows for maximum operating pressure up to 5000 psi (350 bar). Its typical response time is around 50 ms with maximum leakage at specified conditions being minimal. Ideal for applications requiring high switching frequency up to 15,000 cycles per hour, this valve ensures robust performance and reliability in demanding 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.
