The Sun Hydraulics DMDAXAV298 (DMDAXAV298) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for the same, ensuring durability and reliability in demanding applications. The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. With a flow capacity of up to 12 gpm (45 L/min) and typical response times of 50 ms, the DMDAXAV298 offers efficient control for hydraulic systems. It does not require a minimum hydraulic pressure to operate, making it versatile for various installation environments. The manual override feature in models with D or L control uses a detent mechanism designed primarily for temporary actuation, with an estimated mechanical life expectancy of about 7,000 cycles. This model incorporates EPDM seals suitable for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. Additionally, the wet armature design of the valve means that the working fluid surrounds the armature which could lead to breakdowns if exposed to high temperatures for extended periods\u2014something to consider depending on the operational environment. The DMDAXAV298 also features interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Its design includes Sun's floating style construction which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. This robust construction along with its high switching frequency capability makes it an ideal choice for dynamic systems requiring precise control and frequent operation.

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.
