The Sun Hydraulics DNDATSN814 (DNDATSN814) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. It is engineered for high-performance applications with a fatigue-rated solenoid tube assembly capable of operating at pressures up to 5000 psi (350 bar). This valve does not require minimum hydraulic pressure for operation, providing versatility in various systems. It includes several manual override options, though it's important to note that these are incompatible with weatherized coils. The manual control assembly has an estimated mechanical life of approximately 7,000 cycles and requires a force of 5 lbs/1000 psi for actuation. This valve employs a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil. This feature should be considered in applications where the coil remains energized for extended periods, as certain fluids may degrade over time at elevated temperatures. The DNDATSN814 offers various coil termination and voltage options, with interchangeable coils across Sun Series 1 products that can be mounted in either direction. The valve's construction utilizes Sun's floating style to minimize internal binding due to installation torque or machining variations. It is designed to handle a flow capacity of up to 10 gpm (40 L/min) with a typical response time of 50 ms and can achieve switching frequencies up to 15,000 cycles per hour. The maximum valve leakage rate is specified at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Installation requires a torque range of 30-35 lbf-ft (41-47 Nm), and the unit has a compact form factor with dimensions including a solenoid tube diameter of .75 inches (19 mm) and weighs .60 lb (0.30 kg).

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.
