The Sun Hydraulics DMDADBN224 (DMDADBN224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its responsiveness and reliability across applications. It features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring durability and longevity in demanding environments. The valve incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The model is equipped with either D or L control options; both include a manual override with a detent mechanism primarily intended for temporary actuation. This manual system has a mechanical life expectancy of approximately 7,000 cycles. Designed with EPDM seals, the DMDADBN224 is specifically suited for use with phosphate ester fluids; however, these seals are vulnerable to damage if exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature which could be susceptible to heat buildup during extended coil energization periods. This model boasts interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. It also utilizes Sun's floating style construction to minimize internal parts binding which might occur due to excessive installation torque or machining variations in the cavity/cartridge setup. With a switching frequency capability of up to 15,000 cycles per hour and quick typical response times of 50 ms, this valve ensures efficient operation in various hydraulic systems while maintaining maximum operating pressures up to 5000 psi (350 bar) and flow capacities up to 12 gpm (45 L/min).

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.
