The Sun Hydraulics DMDATBN924 (DMDATBN924) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust service with a fatigue rating for 5000 psi (350 bar). It features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It includes options for manual override through the D or L control, although the detent mechanism in these models is intended only for temporary actuation with a mechanical life expectancy of about 7,000 cycles. This model also supports EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. A notable feature of the DMDATBN924 is its wet armature design which immerses the armature in working fluid, potentially affecting performance if the coil remains energized extensively. The valve's design incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This unit has a capacity of 12 gpm (45 L/min), with a typical response time of 50 ms and can handle switching frequencies up to 15,000 cycles/hr. The manual override requires a force of about 5 lbs at 1000 psi on Port 1 and features a stroke length of .10 inches (2.5 mm). The solenoid tube measures .75 inches (19 mm) in diameter, and the valve requires an installation torque between 30-35 lbf ft (41-47 Nm). Weighing just .60 lb (0.30 kg), the DMDATBN924 offers compact yet powerful operation suitable for demanding 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.
