The Sun Hydraulics DNDATRV712N (DNDATRV712N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring robust performance in demanding applications. This valve operates without the need for minimum hydraulic pressure, making it versatile across various systems. A range of manual override options is available, though not all are compatible with weatherized coils. Notably, models with D or L controls include a detent mechanism intended for temporary actuation with an approximate mechanical life expectancy of 7,000 cycles. The valve incorporates EPDM seals specifically for use with phosphate ester fluids; these seals are susceptible to damage from petroleum-based substances. The wet armature design allows the working fluid to surround the armature, which can be influenced by coil-generated heat during extended energization periods\u2014this is particularly relevant for fluids like water-glycol mixtures that may degrade and form varnishes over time. Offering high efficiency due to its unique magnetic design, this solenoid achieves significant spool actuating force per watt expended, ensuring reliable valve shifting. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. The availability of coil connector options extends up to IP69K ratings for enhanced environmental protection. Technical specifications include a cavity size of T-31A and a capacity of 10 gpm (40 L/min). The valve's response time is typically 50 ms with maximum leakage at 110 SUS (24 cSt) limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports switching frequencies up to 15,000 cycles per hour and requires a manual override force of 5 lbs/1000 psi at Port 1. The model weighs approximately .60 lb (.30 kg) and includes Viton seal kits for both cartridge and coil components.

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.
