The Sun Hydraulics DMDATAN297 (DMDATAN297) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to offer robust control in various hydraulic systems. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it is suitable for demanding applications requiring precise fluid control. The valve features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDATAN297 incorporates a wet armature design allowing the working fluid to surround the armature, which can be crucial when considering the thermal effects during prolonged energization of the coil. It's important to note that this design may affect certain fluids under extended operation. The unit\u2019s manual override mechanism is designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles, making it reliable for emergency or maintenance operations. Equipped with EPDM seals, this valve is specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for easier maintenance and replacement processes. Additionally, its floating style construction minimizes internal parts binding which could occur due to installation torque or machining variations in cavity-cartridge setups. Overall, the Sun Hydraulics DMDATAN297 valve offers a durable and efficient solution for directing flow in hydraulic systems where high performance and reliability are essential.

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.
