The Sun Hydraulics DMDADBN924 (DMDADBN924) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring durability and reliability under high-pressure conditions. The valve is characterized by its closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDADBN924 operates without requiring a minimum hydraulic pressure, enhancing its versatility across different hydraulic systems. It includes options for manual override controls (D, L, T types), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from petroleum-based substances. A notable feature of this model is its wet armature design; the armature is immersed in the working fluid which helps manage the heat generated by the coil but requires consideration of fluid type to avoid breakdowns that could impair functionality. Additionally, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. The construction incorporates Sun\u2019s floating style design minimizing internal parts binding caused by excessive installation torque or machining variations. With a maximum operating pressure of 5000 psi and a flow capacity of 12 gpm (45 L/min), along with rapid response times typically around 50 ms and switching frequency up to 15000 cycles/hr, the DMDADBN924 is an effective solution for advanced hydraulic systems requiring robust and precise control.

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.
