The Sun Hydraulics DMDAXRV648 (Material Number DMDAXRV648) is a solenoid-operated 3-way, 2-position cartridge valve characterized by its direct-acting, balanced spool design. This valve is engineered to operate efficiently without requiring a minimum hydraulic pressure, making it highly versatile for various applications. It features a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi or 350 bar, ensuring durability and reliability under high-pressure conditions. The DMDAXRV648 incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model also includes manual override options with a detent mechanism designed for temporary actuation, with the mechanical life expectancy of the control assembly around 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from petroleum-based substances. The valve's wet armature design allows the working fluid to surround the armature which could be relevant in scenarios where the coil remains energized over extended periods; special attention might be necessary for fluid maintenance to prevent breakdown and varnish formation. Furthermore, the DMDAXRV648 valve supports interchangeable coils with other Sun Series 1 solenoid products and features a construction that minimizes internal parts binding due to installation variances. This model offers a flow capacity of up to 12 gpm (45 L/min) and allows for rapid switching frequencies up to 15,000 cycles per hour. The compact design includes a manual override feature requiring minimal force and provides quick response times typical at around 50 ms. Its robust construction and thoughtful engineering make it an adaptable solution for sophisticated hydraulic systems demanding precise control and reliability.

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.
