The Sun Hydraulics DMDAXRN298 (DMDAXRN298) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is equipped with a fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar). The valve features closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. The DMDAXRN298 operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It includes optional manual override controls (D, L, T types) which are primarily intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve is compatible with EPDM seals suited for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. This model utilizes a wet armature design where the working fluid surrounds the armature. Special attention should be given if the coil remains energized over extended periods as heat buildup can degrade certain types of hydraulic fluids. For ease of maintenance and adaptability, the solenoid coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction. Additionally, the DMDAXRN298 incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This design detail ensures reliable operation and longevity of the valve in demanding operational conditions. With specifications like a flow capacity of up to 12 gpm (45 L/min) and a typical response time of 50 ms, this valve is an efficient choice for advanced hydraulic setups requiring precise control and robustness.

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.
