The Sun Hydraulics DNDAMUE948 (DNDAMUE948) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This valve is engineered for high-performance applications with its solenoid tube assembly fatigue-rated for 5000 psi (350 bar) service. It operates without requiring minimum hydraulic pressure and offers various manual override options, though manual overrides are not compatible with weatherized coils. The detent mechanism in the manual override is intended for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. The valve's EPDM seals are suitable for systems using phosphate ester fluids but can be damaged by petroleum-based substances. Its wet armature design allows the working fluid to surround the armature, which may affect function if exposed to heat from long-term coil energization. With coil termination and voltage options available, including surge protection, this valve ensures reliable operation through its efficient magnetic solenoid design that delivers high spool actuating force per watt. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction, offering IP69K-rated connector options for enhanced environmental protection. The cartridge utilizes Sun\u2019s floating style construction to minimize binding risks due to installation torque or machining variations. The DNDAMUE948 fits into a T-31A cavity and belongs to Series 1 with a capacity of 10 gpm (40 L/min). It supports maximum operating pressures of up to 5000 psi (350 bar) with typical response times of 50 ms and a switching frequency of up to 15,000 cycles/hr. Valve leakage at specific conditions is minimal at 10 in\u00b3/min (160 cc/min). Installation requires torque between 30-35 lbf ft (41-47 Nm), and 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.
