The Sun Hydraulics DMDALPN298 (DMDALPN298) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and precise performance in hydraulic systems. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve offers closed transitions between Spools B and R, which optimizes performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. With a maximum flow capacity of 12 gpm (45 L/min) and a rapid typical response time of 50 ms, the DMDALPN298 excels in applications requiring quick and efficient fluid control. It incorporates Sun's floating style construction which minimizes internal parts binding, thus enhancing reliability even with installation torque and machining variations. The valve's wet armature design means that the working fluid surrounds the armature; this design consideration is crucial in applications where the coil may be energized for extended periods as it affects fluid integrity over time. The manual override feature of this model includes a detent mechanism designed for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based fluids. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction for flexible installation options. This model also supports an impressive switching frequency of up to 15,000 cycles per hour and has stringent leakage controls at high pressures (5 in\u00b3/min at 3000 psi). The compact design includes essential features like a .75 inch solenoid tube diameter and requires an installation torque between 30-35 lbf-ft., making it both practical and easy to integrate into various hydraulic systems without requiring extensive modifications.

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.
