The Sun Hydraulics DMDADRN223 (DMDADRN223) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is notable for its ability to operate without minimum hydraulic pressure, making it highly effective in a variety of operational contexts. The valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring durability and reliability even under strenuous conditions. The DMDADRN223 integrates closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times particularly useful in pilot control applications where capacity is less critical. Additionally, the valve incorporates a wet armature design which helps in heat management but requires consideration regarding the type of fluid used; specifically, it's configured with EPDM seals ideal for phosphate ester fluids but vulnerable to damage from petroleum-based substances. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for easy maintenance and replacement. The construction includes Sun\u2019s floating style design which minimizes internal parts binding\u2014a common issue due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), a maximum operating pressure of 5000 psi (350 bar), and a swift typical response time of approximately 50 ms. This valve is also equipped with manual override capabilities featuring a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. The manual override requires minimal force and offers precise control, crucial for situations requiring manual intervention. Overall, the Sun Hydraulics DMDADRN223 offers a reliable solution for directing flow within hydraulic systems across various application settings.

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.
