The Sun Hydraulics DNDAMYN248 (DNDAMYN248) is a solenoid-operated 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional design. Engineered for high performance, the valve's solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. This valve features a wet armature design that allows the working fluid to surround the armature, which can influence performance if the coil is energized for extended periods. Notably, it supports a variety of coil termination and voltage options, with some configurations offering surge protection and weather resistance up to IP69K. The DNDAMYN248 valve does not require a minimum hydraulic pressure for operation, making it versatile for various systems. It also offers several manual override options; however, these are not compatible with weatherized coils. The manual control assemblies have an estimated mechanical life expectancy of around 7,000 cycles. The cartridge's construction incorporates Sun's floating style design to minimize internal part binding due to excessive installation torque or cavity-cartridge machining variations. This model accommodates systems with phosphate ester fluids using EPDM seals but should avoid exposure to petroleum-based fluids. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this valve is suitable for applications requiring rapid actuation and high efficiency. The interchangeable coils can be mounted in either direction on the tube and are compatible with other Sun Series 1 solenoid products. Additionally, the valve has specific installation requirements including a torque range of 30-35 lbf ft (41-47 Nm) and comes with seal kits available in Viton material for enhanced durability under various 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.
