The Sun Hydraulics DMDADPN948 (DMDADPN948) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. Specifically designed for robust industrial applications, this direct-acting, balanced spool directional valve is 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). Notably featuring a fatigue-rated solenoid tube assembly for demanding environments, the DMDADPN948 ensures reliable operation with its closed transition between spool positions B and R, enhancing performance by ensuring faster and more consistent response times particularly in pilot control applications. This model is equipped with manual override options including detent mechanisms in the D or L control setups suited for temporary actuation. With an expected mechanical life of approximately 7,000 cycles for these controls, it is built for durability and sustained performance. The valve also utilizes EPDM seals recommended for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Another key feature of the DMDADPN948 is its wet armature design which involves the working fluid surrounding the armature. This design consideration is crucial when the coil is energized over extended periods as it can lead to breakdowns in certain fluid types like water-glycol mixtures. For ease of integration with existing systems, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, Sun's floating style construction minimizes internal parts binding which could occur due to excessive installation torque or cavity/cartridge machining variations.

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.
