The Sun Hydraulics DMDADAN298 (DMDADAN298) is a solenoid-operated 3-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional control mechanism. This model is specifically designed for high-performance applications with a fatigue rating for 5000 psi (350 bar) service, ensuring reliability and durability under intense operational conditions. The DMDADAN298 features closed spools B and R during the transition between positions, which enhances performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The valve operates without a minimum hydraulic pressure requirement, making it versatile for various fluid power applications. It incorporates a wet armature design; the working fluid surrounds the armature which helps in heat dissipation but requires careful consideration of fluid type to avoid breakdown and varnish formation that could impair functionality. Notably, cartridges with EPDM seals are compatible with phosphate ester fluids but should not be used with petroleum-based fluids to prevent seal damage. This model supports interchangeable coils with other Sun Series 1 solenoid products and allows mounting on the tube in either direction to accommodate different installation needs. The construction includes Sun\u2019s floating style which minimizes internal parts binding due to installation torque or cavity-cartridge machining variations. The DMDADAN298 offers a flow capacity of up to 12 gpm (45 L/min) and features manual override options with a mechanical life expectancy of around 7,000 cycles for models equipped with D, L, or T control assemblies. This makes it a robust choice for various hydraulic systems requiring precise control and reliable operation 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.
