The Sun Hydraulics DMDAMAN298 (DMDAMAN298) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in a variety of applications. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its versatility across different operational settings. The valve features a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. With a switching frequency of up to 15,000 cycles per hour and a typical response time of 50 ms, the DMDAMAN298 offers rapid and consistent actuation vital for efficient system performance. It has an operational capacity of 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). The manual override feature requires minimal force, approximately 5 lbs at 1000 psi for Port 1, facilitating easy operation during temporary manual actuation. The construction of the DMDAMAN298 incorporates Sun's unique floating style design which minimizes internal part binding due to installation torque or variances in cavity/cartridge machining. This feature contributes significantly to the longevity and maintenance ease of the valve. Additionally, the wet armature design allows for interchangeability with other Sun Series 1 solenoid products and supports mounting flexibility. Seal options include EPDM for systems using phosphate ester fluids; however, these seals are susceptible to damage from petroleum-based fluids. For environments demanding robustness against such materials, alternative seals are recommended. The compact size (.60 lb weight) and robust construction make this valve an excellent choice for applications requiring reliable directional control in confined spaces with stringent performance criteria.

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.
