The Sun Hydraulics DMDADBN924N (DMDADBN924N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is notable for its fatigue rating at 5000 psi (350 bar), making it suitable for high-pressure environments. The DMDADBN924N features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. This model is direct actuated and operates independently of hydraulic pressure. It includes options for manual override with a detent mechanism designed for temporary actuation; these controls (D, L, and T) have a mechanical life expectancy of about 7,000 cycles. The DMDADBN924N is equipped with EPDM seals intended specifically for use with phosphate ester fluids; exposure to petroleum-based substances can damage these seals. The valve utilizes a wet armature design which means the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods due to heat exposure. It supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include a maximum flow capacity of 12 gpm (45 L/min), quick response time typically around 50 ms, and maximum leakage at 3000 psi set at 5 in\u00b3/min. Designed with Sun's floating style construction, the DMDADBN924N minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. This model's practical design ensures reliability and efficiency in controlling fluid power in various hydraulic systems.

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.
