The Sun Hydraulics DMDATBN223 (DMDATBN223) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust hydraulic system applications, providing precise control and reliable operation. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), the valve is well-suited for heavy-duty operations. The DMDATBN223 features an innovative wet armature design where the working fluid surrounds the armature, aiding in heat management during prolonged coil energization. However, care must be taken with fluid selection as water-glycol mixtures may degrade under high temperatures. The model incorporates EPDM seals specifically for use with phosphate ester fluids, ensuring compatibility and longevity in specified environments. This valve also boasts interchangeable coils with other Sun Series 1 solenoid products, enhancing its versatility and ease of integration into existing systems. The manual override option, equipped with a detent mechanism in models with D or L control, is designed for temporary actuation and supports about 7,000 cycles mechanically. Additional features such as the floating style construction minimize internal parts binding due to installation torque or machining variations of cavity/cartridge. This ensures consistent performance and reliability even under challenging installation conditions. With its quick response time of approximately 50 ms and minimal leakage at high pressures (5 in\u00b3/min at 3000 psi), the DMDATBN223 is an excellent choice for applications requiring fast and precise control in 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.
