The Sun Hydraulics DNDATDN236 (DNDATDN236) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct acting and balanced spool directional control. This valve is engineered to operate under a maximum pressure of 5000 psi (350 bar) without the need for minimum hydraulic pressure, offering versatility in various hydraulic systems. It features a fatigue-rated solenoid tube assembly and incorporates a wet armature design to ensure efficient heat dissipation from the coil. The valve supports multiple manual override options, though it is important to note that manual overrides are not compatible with weatherized coils. With an expected mechanical life of approximately 7,000 cycles for certain manual controls, this component promises durability. The DNDATDN236 has a capacity of 10 gpm (40 L/min) and offers rapid response times typical at 50 ms. It can handle switching frequencies up to 15,000 cycles per hour with minimal leakage rates at specified conditions. The valve's construction includes Sun's floating style design to reduce the risk of internal binding during installation or due to machining variations. Coil interchangeability with other Sun Series 1 products adds flexibility in configuration, with options for coil termination and voltages available, some providing surge protection and IP69K ratings. This cartridge valve is suitable for systems using phosphate ester fluids when equipped with EPDM seals; exposure to petroleum-based fluids should be avoided as it may damage the seals. Its high-efficiency solenoid design ensures reliable performance by maximizing spool actuating force relative to energy consumption. The model has a compact size with specific installation requirements such as a .75-inch solenoid tube diameter and .78-inch hex size, along with a weight of .60 lb (.30 kg).

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.
