The Sun Hydraulics DMDAMNN848 (DMDAMNN848) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is uniquely engineered to handle a maximum operating pressure of 5000 psi (350 bar) and offers a flow capacity of up to 12 gpm (45 L/min). The DMDAMNN848 operates with no minimum hydraulic pressure requirement, making it highly effective for various applications. Constructed with durability in mind, the solenoid tube assembly of this model is fatigue rated for demanding conditions. It includes spools B and R that remain closed during transition between positions to enhance performance at the cost of lower capacity. However, this characteristic proves beneficial in pilot control applications by ensuring faster and more consistent response times. The typical response time for this valve is around 50 ms. This model can be equipped with either D or L control options where the manual override feature has a mechanical life expectancy of about 7,000 cycles. The cartridges that are configured with EPDM seals are specifically designed for systems using phosphate ester fluids; however, they must not be exposed to petroleum-based fluids as this would damage the seals. Additionally, the DMDAMNN848 incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations in cavity/cartridge. It also has interchangeable coils that can be mounted on the tube in either direction enhancing its versatility across different setups. The manual override requires a force of about 5 lbs at 1000 psi for activation and features a stroke length of .10 inches (2.5 mm). Overall, the Sun Hydraulics DMDAMNN848 valve offers robust performance and reliability for specialized hydraulic applications requiring precise control and rapid response times.

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.
