The Sun Hydraulics DNDATNV648 (DNDATNV648) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient directional control in hydraulic systems. This direct-acting, balanced spool valve features a robust solenoid tube assembly rated for fatigue at service pressures up to 5000 psi (350 bar), ensuring high reliability and performance in demanding applications. The valve operates without the need for minimum hydraulic pressure, making it versatile for various system requirements. It offers multiple manual override options, though certain configurations are not compatible with weatherized coils. Notably, models with D or L control include a detent mechanism intended for temporary activation with an approximate mechanical life of 7,000 cycles. The cartridge is designed with EPDM seals suitable for phosphate ester fluid systems but should not be exposed to petroleum-based products to prevent seal damage. Its wet armature design allows the working fluid to cool the coil; however, prolonged energization may affect fluids like water-glycol mixtures due to heat exposure. The solenoid's unique magnetic design enhances efficiency by delivering high actuating force per watt, ensuring reliable operation. This valve supports various coil termination and voltage options, including surge protection features and interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. The floating style construction minimizes potential binding from installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this model is engineered for quick switching at frequencies up to 15,000 cycles per hour. The DNDATNV648's compact size and robust construction make it ideal for applications requiring dependable directional control under high-pressure conditions.

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.
