The Sun Hydraulics DMDADBN524 (DMDADBN524) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. It features a direct-acting, balanced spool directional control that efficiently manages the flow and direction of hydraulic fluid within the system. This model is notable for its robust construction with a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding applications. The valve operates with no minimum hydraulic pressure required, enhancing its versatility in various hydraulic circuits. The DMDADBN524 incorporates advanced design elements such as closed transitions between Spools B and R to optimize performance by providing faster and more consistent response times, particularly useful when applied as pilot controls. Its wet armature design allows the working fluid to surround the armature, which is crucial in scenarios where the valve might be energized continuously. However, this can also lead to breakdowns in certain types of fluids over extended periods. Additionally, the model supports interchangeable coils from other Sun Series 1 solenoid products and features a floating style construction that minimizes internal part binding due to installation variances. The manual override mechanism included in models with D or L control is designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. This valve also offers a switching frequency of up to 15,000 cycles per hour and has manual override specifications that require minimal force, making it user-friendly under various operating pressures. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended while avoiding exposure to petroleum-based substances to prevent seal damage. This model\u2019s thoughtful engineering ensures reliability and efficiency in controlling fluid dynamics across diverse hydraulic applications.

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.
