The Sun Hydraulics DNDAMYV948 (DNDAMYV948) is a solenoid-operated 4-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. This highly efficient valve is designed for robust performance with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. It requires no minimum hydraulic pressure for operation, making it versatile for various applications. The valve features multiple manual override options, including models with temporary actuation detent mechanisms and those without any manual override capabilities. However, note that manual override functionality is incompatible with weatherized coils. This model incorporates a wet armature design where the working fluid surrounds the armature, which can affect performance if the coil remains energized for prolonged periods due to heat exposure. The DNDAMYV948 offers various coil termination and voltage options, ensuring flexibility in different setups and environments. Its high-efficiency solenoid design ensures reliable valve shifting by delivering significant spool actuating force per watt expended. The valve's construction employs Sun's floating style to minimize potential internal part binding due to excessive installation torque or cavity-cartridge machining variations. It fits into a T31A cavity and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The maximum leakage at 110 SUS (24 cSt) is limited to 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar), while the switching frequency can reach up to 15,000 cycles per hour. Additional specifications include a manual override force requirement of 5 lbs/1000 psi at Port 1 and an override stroke of .10 inches (2.5 mm). The solenoid tube diameter is .75 inches (19 mm), with an installation torque range of 30-35 lbf ft (41-47 Nm). The model weighs approximately .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.
