The Sun Hydraulics DMDADBN536 (DMDADBN536) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is fatigue rated for demanding applications up to 5000 psi (350 bar). It features a unique construction with spools B and R closed during the transition between positions, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, enhancing its versatility across various hydraulic setups. Equipped with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids which can damage the seals. The wet armature design of the valve means that the working fluid surrounds the armature, which could affect fluid integrity if the coil remains energized over extended periods. This design consideration is crucial when using water-glycol mixtures or other sensitive fluids. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun's floating style construction to minimize internal parts binding due to installation torque or machining variations of cavity/cartridge. This feature ensures reliable operation and longevity of the component in complex hydraulic systems. With a maximum flow capacity of 12 gpm (45 L/min) and typical response time of 50 ms, along with a mechanical life expectancy of approximately 7,000 cycles for models with D, L or T manual control assembly, this valve stands out as a robust solution for high-frequency switching applications up to 15,000 cycles per hour. The manual override feature requires minimal force and offers precise control in temporary actuation scenarios.

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.
