The Sun Hydraulics DMDADBN (DMDADBN) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered to function efficiently with no minimum hydraulic pressure required for operation, making it highly versatile across various applications. The valve features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The DMDADBN model incorporates closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. Additionally, the valve boasts a quick response time of approximately 50 ms and can handle a flow capacity up to 12 gpm (45 L/min), with maximum operating pressures also reaching 5000 psi (350 bar). For ease of maintenance and adaptability, the DMDADBN's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The design includes Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of the cavity/cartridge. This model also features manual override options with a detent mechanism designed for temporary actuation and has an estimated mechanical life expectancy of about 7,000 cycles. The valve is equipped with EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. With its robust construction and flexible design parameters, the Sun Hydraulics DMDADBN valve stands out as an effective solution for directing flow in hydraulic systems where precision and reliability are paramount.

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.
