The Sun Hydraulics DMDAMNV298 (DMDAMNV298) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure and features a fatigue rating of 5000 psi (350 bar), making it suitable for rigorous industrial uses. The model incorporates closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times particularly when used as pilot controls. The DMDAMNV298 is equipped with interchangeable coils from the Sun Series 1 solenoid products, which can be mounted in either direction on the tube, providing flexibility in installation. It also utilizes a wet armature design where the working fluid surrounds the armature; this design consideration is crucial for applications where the coil may be energized for extended periods. Additional features include a manual override with a detent mechanism designed primarily for temporary actuation. The manual override has an expected mechanical life of approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based fluids. This valve model also benefits from Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), along with rapid response times typically around 50 ms, the DMDAMNV298 is an effective solution for high-demand hydraulic control systems requiring robust and reliable performance.

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.
