The Sun Hydraulics DMDADBV297 (DMDADBV297) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for a minimum hydraulic pressure, enhancing its versatility across various applications. The model features a fatigue rating of 5000 psi (350 bar), making it suitable for demanding environments where robustness and reliability are critical. The DMDADBV297 incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting fluid properties if exposed to heat over prolonged periods. It is crucial to consider the type of fluid used; for instance, EPDM seals in this model are compatible with phosphate ester fluids but should not be used with petroleum-based fluids which can degrade the seals. This valve offers rapid and consistent response times due to its closed transition spools (B and R) between positions, which is particularly beneficial when used as pilot controls. The manual override feature in models equipped with D or L control is designed for temporary actuation and has an expected mechanical life of about 7,000 cycles. Other technical specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum valve leakage at 5 in\u00b3/min at 3000 psi. The interchangeable coils from Sun Series 1 products add to its adaptability, allowing easy maintenance and replacement. Furthermore, the valve's construction minimizes internal part binding due to installation torque or machining variations thanks to Sun's floating style design. Overall, the Sun Hydraulics DMDADBV297 offers a robust solution for efficient directional control in hydraulic circuits requiring high performance and reliability under varying operational conditions.

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.
