The Sun Hydraulics DNDATNV948 (DNDATNV948) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar), ensuring robust performance without the need for minimum hydraulic pressure. This valve offers various manual override options, although manual override is not compatible with weatherized coils. The D, L, and T manual control assemblies have a mechanical life expectancy of about 7,000 cycles. Specifically engineered for systems using phosphate ester fluids, cartridges with EPDM seals should not be exposed to petroleum-based substances as this will damage the seals. The valve employs a wet armature design where the working fluid surrounds the armature and absorbs heat from the coil. This design consideration is crucial when operating in environments where fluid degradation due to heat could affect performance over time. Available in multiple coil termination and voltage configurations, it also boasts high-efficiency solenoids that provide substantial spool actuating force per watt used. The DNDATNV948 supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options offer protection ratings up to IP69K for enhanced environmental resistance. The valve incorporates Sun's floating style construction to minimize internal binding risks caused by excessive installation torque or machining variations. With a cavity size of T-31A and a capacity of 10 gpm (40 L/min), this model can handle maximum operating pressures of up to 5000 psi (350 bar) and features a typical response time of 50 ms. Its switching frequency reaches up to 15,000 cycles/hr, while maintaining minimal valve leakage at specified conditions. The model weighs approximately .60 lb (.30 kg) and requires specific torque settings for installation to ensure optimal performance.

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.
