The Sun Hydraulics DMDAMNV297 (DMDAMNV297) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a robust construction that is fatigue rated for 5000 psi (350 bar) service, ensuring reliability and durability in demanding applications. The valve operates with no minimum hydraulic pressure required, making it versatile for various operational setups. Equipped with EPDM seals, the DMDAMNV297 is specifically configured for use with phosphate ester fluids; however, it is important to avoid exposure to petroleum-based fluids which can damage the seals. The valve's wet armature design allows the working fluid to surround the armature, helping manage heat during prolonged coil energization but requires consideration of fluid characteristics as some may degrade under heat. This model incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. It also features Sun's floating style construction which minimizes internal parts binding that could occur due to excessive installation torque or cavity/cartridge machining variations. The DMDAMNV297 has a flow capacity of up to 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Its quick response time of approximately 50 ms and switching frequency of up to 15000 cycles/hr make it suitable for applications requiring rapid directional changes. Additionally, manual override options are available with a mechanical life expectancy of about 7,000 cycles for temporary actuation needs. This model ensures consistent performance and reliability in hydraulic circuit operations where high speed and precision are critical.

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.
