The Sun Hydraulics DMDADAV298 (DMDADAV298) is a solenoid-operated 3-way, 2-position cartridge valve that excels in applications requiring direct-acting, balanced spool directional control. This model is specifically designed 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 DMDADAV298 features a fatigue-rated solenoid tube assembly suitable for high-pressure service, ensuring reliability and performance under demanding conditions. This valve's design includes closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The manual override options available with the D or L control are intended for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. It is important to note that cartridges equipped with EPDM seals are compatible with systems using phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. Additionally, the DMDADAV298 utilizes a wet armature design which helps in heat management but requires consideration regarding the type of fluid used due to potential breakdowns at high temperatures. The interchangeable coils compatible with other Sun Series 1 solenoid products add versatility to this model. The construction incorporates Sun\u2019s floating style to minimize internal binding risks caused by installation torque or machining variations of the cavity/cartridge. With its robust build and efficient design, the DMDADAV298 provides a reliable solution for various hydraulic control applications.

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.
