The Sun Hydraulics DNDATDN211 (DNDATDN211) is a solenoid-operated 4-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This valve is engineered for high-performance applications, with a solenoid tube assembly fatigue-rated for up to 5000 psi (350 bar). It operates efficiently without requiring minimum hydraulic pressure and features multiple manual override options. Notably, the manual override on models with D or L control is intended for temporary actuation and offers a mechanical life expectancy of around 7,000 cycles. The valve's design includes EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. Incorporating a wet armature design, the valve allows working fluid to surround the armature, which can impact performance if the coil remains energized over extended periods. Various coil termination and voltage configurations are available to suit different operational needs, including options with surge protection. The high-efficiency solenoid offers substantial spool actuating force per watt expended, ensuring reliable shifting of the valve. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction. The DNDATDN211 features Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar). Typical response time is approximately 50 ms, with maximum leakage at specified conditions being 10 in\u00b3/min (3000 psi). This robust valve supports applications requiring frequent switching, 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.
