The Sun Hydraulics DMDAXRV624N (DMDAXRV624N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for precise control in hydraulic systems. Its solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The valve features a wet armature design, allowing the working fluid to surround the armature and manage heat effectively, although care must be taken with certain fluids that may degrade at higher temperatures. The DMDAXRV624N offers closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. It operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. This model includes interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube for flexible installation options. It also incorporates Sun\u2019s floating style construction which minimizes internal parts binding, a common issue caused by excessive installation torque or cavity/cartridge machining variations. Key specifications of the DMDAXRV624N include a maximum operating pressure of 5000 psi (350 bar), a flow capacity of up to 12 gpm (45 L/min), and typical response times of 50 ms. The valve supports switching frequencies up to 15000 cycles/hr and has manual override capabilities with specific force and stroke requirements for temporary actuation. Designed for robust performance in demanding applications, this valve is an excellent choice for systems requiring reliable directional control with high switching frequency capability.

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.
