The Sun Hydraulics DNDATXV712 (DNDATXV712) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is engineered for high-performance applications, with the solenoid tube assembly fatigue rated for up to 5000 psi (350 bar) service. A key advantage of this model is its direct actuation, which requires no minimum hydraulic pressure to operate. The valve offers several manual override options, although manual override functionality is not compatible with weatherized coils. Notably, models equipped with the D or L control have a detent mechanism in the manual override designed for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. The DNDATXV712 uses EPDM seals suitable for systems utilizing phosphate ester fluids; these seals are susceptible to damage from petroleum-based fluids. The wet armature design allows the working fluid to surround the armature and absorb heat generated by the coil\u2014important when the coil is energized over extended periods. This feature may affect certain fluids like water-glycol mixtures that break down at elevated temperatures. Offering versatility in coil termination and voltage options\u2014with or without surge protection\u2014the valve supports various environmental conditions. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction. Coil connector options provide ratings up to IP69K for enhanced durability against harsh environments. This cartridge incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min), a typical response time of 50 ms, and a switching frequency of up to 15,000 cycles per hour, this model delivers robust performance suitable for demanding applications requiring precise directional control under high-pressure 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.
