The Sun Hydraulics DMDAXBV297 (DMDAXBV297) is a solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This directional valve is characterized by its high-performance capabilities due to closed transitions between Spools B and R. The closed transitions prevent flow in the middle position, optimizing response times which are crucial when used as pilot controls in hydraulic systems. This model is designed to operate without minimum hydraulic pressure, making it highly effective in a variety of applications where consistent operation is needed irrespective of system pressure. It features a fatigue rating for up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The manual override options available with this valve include D, L, and T controls, with an estimated mechanical life expectancy of around 7,000 cycles. The valve\u2019s wet armature design allows the working fluid to surround the armature which can be critical when considering the type of fluid used; for instance, EPDM seals in this model are suitable only for phosphate ester fluids and should not be exposed to petroleum-based fluids. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products add versatility and ease of maintenance. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve is an efficient choice for systems requiring precise control over fluid direction. The construction incorporates Sun\u2019s floating style to minimize internal binding due to installation variances or torque issues. This model also supports a manual override feature requiring minimal force which adds an extra layer of operational security and user control.

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.
