The Sun Hydraulics DMDAMAV648 (DMDAMAV648) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve ensures reliable operation with its fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R, optimizing performance by allowing faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. With no minimum hydraulic pressure required for operation, the DMDAMAV648 offers versatility in integration and functionality. The model equipped with manual override options (D or L control) includes a detent mechanism designed for temporary actuation, supporting a mechanical life expectancy of approximately 7,000 cycles. Additionally, this valve model can be configured with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. The wet armature design of the DMDAMAV648 means that the working fluid surrounds the armature which may affect certain fluid types if exposed to heat over extended periods. This valve is compatible with other Sun Series 1 solenoid products regarding interchangeable coils which can be mounted in either direction on the tube. It also incorporates Sun\u2019s floating style construction that minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This model has a flow capacity of 12 gpm (45 L/min), operates efficiently with a maximum operating pressure of 5000 psi (350 bar), and features typical response times of around 50 ms. Its robust design and interchangeable components make it an excellent choice for demanding hydraulic applications requiring 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.
