The Sun Hydraulics DMDATPN848 (DMDATPN848) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool directional control mechanism. This valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for the same, making it suitable for rigorous applications. It features a flow capacity of up to 12 gpm (45 L/min), and its response time is typically around 50 ms. The DMDATPN848 incorporates a wet armature design allowing the working fluid to surround the armature, which helps in cooling but requires consideration regarding fluid type due to potential breakdowns from prolonged heat exposure. It uses EPDM seals configured specifically for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model's versatility extends through its compatibility with other Sun Series 1 solenoid products concerning interchangeable coils, which can be mounted on the tube in either orientation. The construction includes Sun's floating style design that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Additionally, the manual override feature included in this model has a mechanical life expectancy of approximately 7,000 cycles and requires an override force of about 5 lbs at 1000 psi at Port 1. The manual override stroke measures at .10 inches (2.5 mm), providing efficient temporary actuation when needed. Overall, the DMDATPN848 offers robust performance and reliability for applications requiring precise hydraulic control with minimal transition leakage and consistent operational characteristics under high-pressure conditions.

This solenoid-operated 3-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.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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 configured 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
