The Sun Hydraulics DNDATZN814 (DNDATZN814) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is engineered for high efficiency and reliability, with a solenoid tube assembly that is fatigue-rated for service up to 5000 psi (350 bar). It requires no minimum hydraulic pressure for operation and offers several manual override options, although manual overrides are not compatible with weatherized coils. The valve's EPDM seals are designed specifically for use in systems utilizing phosphate ester fluids and should not be exposed to petroleum-based fluids. The DNDATZN814 incorporates a wet armature design where the working fluid surrounds the armature, which can influence the function if exposed to prolonged coil-generated heat. It offers versatile coil termination and voltage options with surge protection capabilities. The unique magnetic design of the solenoid delivers high spool actuating force per watt, ensuring reliable shifting of the valve. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This cartridge valve is constructed using Sun's floating style to reduce the risk of internal parts binding due to installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1, with a capacity of 10 gpm (40 L/min). The response time is typically around 50 ms, while the maximum valve leakage at 110 SUS (24 cSt) is limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The DNDATZN814 supports a switching frequency of up to 15,000 cycles per hour and has specific manual override force requirements and stroke measurements.

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.
