The Sun Hydraulics DMDAMRV624N (DMDAMRV624N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool directional control. It features a robust construction that is fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The valve offers precise control with closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly in pilot control setups where capacity is less critical. This model incorporates a wet armature design, allowing the working fluid to surround the armature and dissipate heat generated by the coil, although care must be taken with certain fluids that may degrade under prolonged exposure to heat. The DMDAMRV624N is equipped with interchangeable coils compatible with other Sun Series 1 solenoid products and features a floating style construction which minimizes internal parts binding due to installation torque or machining variations. The valve supports a maximum flow capacity of 12 gpm (45 L/min) and offers quick response times, typically around 50 ms. It also boasts minimal leakage at high pressures and can handle up to 15000 switching cycles per hour. Manual override options are available, requiring minimal force, and are intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based substances. Overall, the Sun Hydraulics DMDAMRV624N combines durability, flexibility, and precision control in hydraulic system 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.
