The Sun Hydraulics DMDATBN824 (DMDATBN824) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate seamlessly within a maximum pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). The valve features closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for applications where capacity is less critical. Equipped with EPDM seals, the DMDATBN824 is specifically configured for use with phosphate ester fluids, ensuring compatibility and longevity in specific fluid environments while avoiding damage from petroleum-based substances. The model also incorporates a wet armature design which surrounds the armature with working fluid to manage heat during prolonged energization periods, although care must be taken with certain fluids that may degrade under heat. The DMDATBN824 offers interchangeable coils compatible with other Sun Series 1 solenoid products and features a manual override mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. It also utilizes Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. This valve is an ideal choice for systems requiring robust control with minimal hydraulic pressure for operation. Its quick response time of about 50 ms and maximum leakage specification of 5 in\u00b3/min at 3000 psi ensure efficient performance. The switching frequency can reach up to 15,000 cycles per hour, demonstrating its capability for high-frequency operations. This model also supports manual override requirements with minimal force, adding to its operational flexibility and ease of use in various hydraulic control 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.
