The Sun Hydraulics DMDADRV224 (DMDADRV224) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. The valve features a direct-acting, balanced spool with closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times ideal for applications where capacity is not the primary concern. This design choice makes it particularly suited for use as pilot controls in various hydraulic systems. Engineered to operate without minimum hydraulic pressure, the DMDADRV224 ensures reliable functionality in diverse operating conditions. The model includes a manual override with a detent mechanism intended for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. Additionally, it is compatible with EPDM seals specifically designed for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The DMDADRV224 employs a wet armature design where the working fluid surrounds the armature; this aspect needs consideration as prolonged coil energization can lead to fluid degradation at high temperatures. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube assembly. Moreover, it incorporates Sun's floating style construction to minimize internal part binding due to installation or machining variations. This valve supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features rapid response times typically around 50 ms and maintains low leakage rates even under high pressure. For ease of maintenance and replacement, the valve dimensions include a solenoid tube diameter of .75 inches (19 mm) and uses standard Viton seal kits for enhanced durability and performance under various environmental conditions.

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.
