The Sun Hydraulics DNDATHV836 (DNDATHV836) is a solenoid-operated 4-way, 2-position cartridge valve known for its direct-acting, balanced spool design. It is engineered for high-performance applications with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). This valve doesn't require a minimum hydraulic pressure for operation, making it versatile for various hydraulic systems. It offers multiple manual override options, although manual override is not compatible with weatherized coils. The detent mechanism in the D and L control models is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve's wet armature design allows working fluid to surround the armature, which can impact fluids like water-glycol mixtures over time due to coil heat exposure. The DNDATHV836 features interchangeable coils compatible with other Sun Series 1 solenoid products and provides numerous coil termination and voltage options, including those with surge protection and IP69K-rated connectors. Its unique magnetic design enhances efficiency by maximizing spool actuating force per watt expended, ensuring reliable valve shifting. Constructed using Sun's floating style technique, it minimizes internal part binding risks caused by excessive installation torque or machining variations within the cavity/cartridge interface. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this cartridge is suitable for high-frequency switching applications up to 15,000 cycles per hour. The valve incorporates EPDM seals ideal for phosphate ester fluids but unsuitable for petroleum-based substances. It's designed to be robust and stable even in challenging conditions, making it an excellent choice for demanding hydraulic 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.
