The Sun Hydraulics DMDADNN536 (DMDADNN536) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that provides precise control and robust functionality in hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. The valve's spools are closed during the transition between positions to enhance performance limits at the cost of reduced capacity. However, this feature benefits applications requiring fast and consistent response times, especially when used as pilot controls where capacity is less critical. The DMDADNN536 operates without needing a minimum hydraulic pressure, making it versatile for various applications. It includes manual override options with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles mechanically. The valve is best suited for systems using phosphate ester fluids when configured with EPDM seals; however, it should not be exposed to petroleum-based fluids as they can damage the seals. This model employs a wet armature design where the working fluid surrounds the armature exposed to heat from the coil\u2014a consideration for long energizing periods as some fluids may degrade and affect performance. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and setup. Additionally, its construction incorporates Sun's floating style to minimize internal parts binding due to installation torque or machining variations of cavity/cartridge. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at 5 in\u00b3/min at 3000 psi. The manual override requires minimal force, and the solenoid tube assembly is compact yet robustly designed for demanding 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.
