The Sun Hydraulics DNDATRV914 (DNDATRV914) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered with a fatigue-rated solenoid tube assembly for service at pressures up to 5000 psi (350 bar), providing reliable performance without the need for minimum hydraulic pressure. It offers several manual override options, although compatibility with weatherized coils is limited. The manual override, particularly in models with D or L control, is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. EPDM seals are available for systems using phosphate ester fluids but should not be exposed to petroleum-based substances to avoid damage. The valve's wet armature design allows fluid to surround the armature, offering efficient heat dissipation from the coil but may affect certain fluids over time. The DNDATRV914 features high-efficiency solenoid operation due to its unique magnetic design, ensuring robust valve shifting with minimal power consumption. This valve accommodates a variety of coil termination and voltage options, including surge protection capabilities. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. For environmental resilience, coil connector options offer ratings up to IP69K and additional weatherized coils and kits are available. This cartridge incorporates Sun's floating style construction to minimize internal component binding from excessive installation torque or cavity-cartridge machining variations. It fits into a T-31A cavity and supports flow capacities up to 10 gpm (40 L/min). With a typical response time of 50 ms and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this model is capable of handling switching frequencies up to 15,000 cycles per hour.

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.
