The Sun Hydraulics DMDADRN224 (DMDADRN224) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. It features a direct-acting, balanced spool with closed transitions between positions, enhancing performance by ensuring faster and more consistent response times particularly suitable for pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. This model boasts a fatigue rating of 5000 psi (350 bar), and it can handle a flow capacity of up to 12 gpm (45 L/min) which suits it well for medium-scale hydraulic tasks. The valve's response time is notably quick at approximately 50 milliseconds, and it supports a switching frequency of up to 15,000 cycles per hour. Additionally, the manual override feature requires minimal force (5 lbs at 1000 psi), facilitating easy operation under varied pressure conditions. The DMDADRN224 valve utilizes EPDM seals recommended for systems using phosphate ester fluids; however, these seals are vulnerable to damage if exposed to petroleum-based fluids. Its wet armature design allows the working fluid to cool the armature, although prolonged exposure could lead to fluid degradation in certain conditions. For enhanced durability and reliability, this model incorporates Sun's floating style construction which minimizes internal part binding due to installation variances or cavity/cartridge machining errors. Interchangeability of coils with other Sun Series 1 solenoid products offers additional flexibility and ease of maintenance. This robust construction combined with versatile features makes the DMDADRN224 an ideal choice for reliable directional control in hydraulic systems across various applications.

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.
