The Sun Hydraulics DNDATUN71299 (DNDATUN71299) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate without the need for minimum hydraulic pressure and features a solenoid tube assembly that is fatigue-rated for up to 5000 psi (350 bar) service. It offers various manual override options, though these are not compatible with weatherized coils. The manual control assembly, specifically the D, L, and T controls, provides a mechanical life expectancy of approximately 7,000 cycles. The valve incorporates EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based fluids as this can damage the seals. The design includes a wet armature system where working fluid surrounds the armature, exposing it to heat generated by the coil\u2014a consideration for long-term coil energization as certain fluids may degrade under these conditions. A wide array of coil termination and voltage options are available, including those with surge protection. The solenoid's magnetic design ensures high efficiency with significant spool actuation force per watt expended. Coils can be interchanged with other Sun Series 1 products and mounted in either direction. This model features Sun's floating style construction to reduce internal part binding due to excessive installation torque or machining variations. It has a cavity size of T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with typical response times around 50 milliseconds and maximum valve leakage at specified conditions being 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). This cartridge supports up to IP69K-rated coil connectors for enhanced environmental protection.

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.
