The Sun Hydraulics DMDATBN924N (DMDATBN924N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for use in hydraulic systems where precise control of fluid flow is necessary. The valve features a fatigue-rated solenoid tube assembly capable of handling service pressures up to 5000 psi (350 bar), making it suitable for high-pressure applications. It operates with a closed transition between its two positions, which enhances performance by providing faster and more consistent response times, particularly when used as pilot controls. The DMDATBN924N requires no minimum hydraulic pressure to function and incorporates a wet armature design, where the working fluid surrounds the armature. This design consideration is crucial as it exposes the fluid to heat generated by the coil, potentially affecting fluid properties over prolonged periods. It's important to note that cartridges configured with EPDM seals should only be used with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model also features interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. Its construction includes Sun\u2019s floating style design which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. With a maximum flow capacity of 12 gpm (45 L/min) and quick typical response times of 50 ms, this valve ensures efficient operation in various hydraulic setups. Additional features include manual override options with a mechanical life expectancy of approximately 7,000 cycles for models equipped with D or L control detents. The manual override requires minimal force and provides a short stroke for temporary actuation, further enhancing the usability and application range of this versatile hydraulic component.

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.
