The Sun Hydraulics DMDATRV224 (DMDATRV224) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring durability and reliability under intense operational conditions. The valve's design incorporates closed transitions between spools B and R, optimizing performance by allowing faster and more consistent response times particularly in pilot control applications where flow capacity is less critical. With a maximum operating pressure of 5000 psi and a flow capacity of 12 gpm (45 L/min), the DMDATRV224 excels in environments requiring precise control. The valve's wet armature design means that the working fluid surrounds the armature; this is an important consideration as it can affect fluid integrity under prolonged coil energization. It is compatible with EPDM seals specifically for use with phosphate ester fluids, though these seals must be protected from exposure to petroleum-based substances to avoid damage. This model also features interchangeable coils with other Sun Series 1 solenoid products, providing flexibility and ease of maintenance. Additionally, its manual override options are designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The construction benefits from Sun's floating style which minimizes internal binding due to installation variances or machining inconsistencies. Overall, the Sun Hydraulics DMDATRV224 offers robust performance and versatility for advanced hydraulic systems requiring reliable directional control and rapid response capabilities.

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.
