The Sun Hydraulics DMDATBV297 (DMDATBV297) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. Featuring a direct-acting, balanced spool design, this valve ensures reliable control in fluid power systems. It is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 12 gpm (45 L/min). The DMDATBV297 operates efficiently with response times typically around 50 ms and exhibits maximum valve leakage at 110 SUS (24 cSt) of approximately 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). This model is equipped with interchangeable coils that are compatible with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. The wet armature design of the valve means that the working fluid surrounds the armature, potentially affecting fluid characteristics if exposed to heat over prolonged periods. This model uses EPDM seals suitable for phosphate ester fluids, while exposure to petroleum-based fluids should be avoided to prevent seal damage. The valve features a manual override function which requires minimal force (5 lbs at 1000 psi for Port 1) and offers a stroke of .10 inches (2.5 mm). Its robust construction incorporates Sun\u2019s floating style design which minimizes internal part binding due to installation torque or machining variations. The manual control assembly promises a mechanical life expectancy of approximately 7,000 cycles, making it suitable for temporary actuation scenarios. With its compact size weighing only .60 lb (0.30 kg), and requiring an installation torque between 30 - 35 lbf.ft (41 -47 Nm), the DMDATBV297 is an ideal choice for applications requiring precise control with durable and reliable performance characteristics in challenging hydraulic environments.

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.
