The Sun Hydraulics DMDATNN848 (DMDATNN848) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is uniquely engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a solenoid tube assembly that is fatigue rated for demanding conditions, ensuring reliability and durability in various operational environments. The DMDATNN848 valve boasts rapid response times with typical response times around 50 ms, making it suitable for applications requiring quick actuation. The design incorporates closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times particularly useful in pilot control setups where capacity is less critical. Additionally, the valve\u2019s wet armature design allows the working fluid to surround the armature, which can be essential in managing the heat generated by the coil during prolonged energization. This model uses EPDM seals suitable for systems with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. For ease of maintenance and compatibility with other systems, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The manual override feature included in models equipped with D or L control is designed primarily for temporary actuation, supporting mechanical life expectancies of approximately 7,000 cycles. This feature along with the Sun floating style construction minimizes internal parts binding which could result from excessive installation torque or cavity/cartridge machining variations. The robust construction and thoughtful engineering make the Sun Hydraulics DMDATNN848 an essential component for advanced hydraulic systems requiring precise control and reliability.

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.
