The Sun Hydraulics DMDADRV624N (DMDADRV624N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design that ensures reliable control in hydraulic systems. The valve operates with no minimum hydraulic pressure required, making it versatile for various applications. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it is suitable for robust industrial environments. The DMDADRV624N incorporates advanced design features such as closed transitions between spools B and R, which enhance performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The valve's wet armature design allows the working fluid to surround the armature, which is beneficial for heat dissipation but requires consideration regarding fluid type due to potential breakdowns from prolonged heat exposure. This model also benefits from interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It employs Sun's floating style construction to reduce internal part binding risks caused by excessive installation torque or variations in cavity/cartridge machining. The manual override feature included in models equipped with D or L control is designed for temporary actuation, supporting a mechanical life expectancy of about 7,000 cycles. Additionally, the DMDADRV624N uses EPDM seals when configured for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. Overall, this valve combines flexibility with durable construction to meet demanding operational requirements effectively.

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.
