The Sun Hydraulics DNDAXNV912 (DNDAXNV912) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a solenoid tube assembly rated for 5000 psi (350 bar) service, making it suitable for high-pressure applications. It operates without the need for minimum hydraulic pressure, providing versatility in various systems. The cartridge offers multiple manual override options, although compatibility with weatherized coils is limited. Models with the D or L control have a detent mechanism intended for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. The valve incorporates EPDM seals to accommodate phosphate ester fluids while cautioning against exposure to petroleum-based substances, which could damage the seals. Its wet armature design allows the working fluid to surround the armature and be exposed to coil-generated heat\u2014a consideration when using water-glycol mixtures that may degrade over time at elevated temperatures. This product offers a range of coil termination and voltage options, some including surge protection. The solenoid's magnetic design ensures high efficiency and reliable valve shifting through substantial spool actuating force per watt expended. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Coil connector options provide ratings up to IP69K for enhanced environmental protection. Constructed with Sun's floating style design, this valve minimizes internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge setups. With a capacity of 10 gpm (40 L/min), response time of approximately 50 ms, and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), it supports efficient fluid control operations in demanding environments.

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.
