The Sun Hydraulics DNDATSN636 (DNDATSN636) is a solenoid-operated 4-way, 2-position cartridge that functions as a direct-acting, balanced spool directional valve. Designed for high-efficiency operation, this valve features a unique magnetic design that maximizes spool actuating force per watt, ensuring reliable valve shifting. It is suitable for systems requiring no minimum hydraulic pressure for operation and can handle a maximum operating pressure of 5000 psi (350 bar). The solenoid tube assembly is fatigue-rated for the same pressure level, making it durable and reliable under demanding conditions. This cartridge supports various manual override options, though it's important to note that manual overrides are incompatible with weatherized coils. For models equipped with D or L control, the detent mechanism in the manual override is intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations. The DNDATSN636 utilizes a wet armature design where the working fluid surrounds the armature, which can be affected by heat from the coil if energized over extended periods. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade at high temperatures. The cartridge offers multiple coil termination and voltage options, some with surge protection and IP69K ratings for enhanced environmental protection. With a capacity of 10 gpm (40 L/min) and typical response time of 50 ms, this valve is designed for high-frequency switching up to 15,000 cycles per hour. It features interchangeable coils compatible with other Sun Series 1 solenoid products and requires an installation torque between 30-35 lbf ft (41-47 Nm). The valve comes equipped with Viton seal kits suitable for use in systems utilizing phosphate ester fluids.

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.
