The Sun Hydraulics DMDALBV648 (DMDALBV648) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient performance with a fatigue rating for 5000 psi (350 bar) service. Key features include closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times when used as pilot controls. This attribute ensures the valve operates effectively even without minimum hydraulic pressure. The DMDALBV648 is equipped with manual override options including D, L, and T controls, with a mechanical life expectancy of around 7,000 cycles for the detent mechanism in manual override. It is important to note that cartridges configured with EPDM seals should only be used with phosphate ester fluids as exposure to petroleum-based fluids can damage these seals. Furthermore, this model incorporates a wet armature design where the working fluid surrounds the armature; this setup helps manage heat but requires consideration regarding fluid type as some may degrade under prolonged exposure to heat. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. Additionally, the DMDALBV648 features Sun's floating style construction which minimizes internal parts binding\u2014a common issue in valves due to installation torque or cavity/cartridge machining variations. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity of up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, this valve is an optimal choice for various 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.
