The Sun Hydraulics DMDAXRV224 (DMDAXRV224) is a solenoid-operated 3-way, 2-position cartridge valve that exemplifies precision and reliability in hydraulic system control. This direct-acting, balanced spool directional valve is designed to operate without the need for minimum hydraulic pressure, making it versatile across various applications. Its solenoid tube assembly is rated for high-pressure fatigue resistance up to 5000 psi (350 bar), ensuring durability and performance under demanding conditions. With a maximum flow capacity of 12 gpm (45 L/min) and a typical response time of 50 ms, the DMDAXRV224 offers efficient control for systems requiring quick directional changes. The valve features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times at the cost of lower capacity\u2014which is typically not a limiting factor in pilot control applications. This model incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations in the cavity/cartridge interface. The manual override feature included in models with D, L, or T controls has a mechanical life expectancy of about 7,000 cycles and is intended for temporary actuation only. The valve uses EPDM seals suitable for systems with phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. It utilizes a wet armature design where the working fluid surrounds the armature exposed to coil-generated heat. Interchangeable coils with other Sun Series 1 solenoid products add to its adaptability, allowing mounting on the tube in either direction. With its robust construction and versatile design features, the DMDAXRV224 is engineered to meet stringent operational demands while providing reliable performance across various hydraulic 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.
