The Sun Hydraulics DMDALPV648 (DMDALPV648) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for various hydraulic applications. This direct-acting, balanced spool directional valve operates without the need for a minimum hydraulic pressure, enhancing its versatility in different system conditions. It features a fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure applications. The valve's design includes closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times especially useful in pilot control setups where capacity is less critical. The model incorporates a wet armature design; hence the working fluid surrounds the armature which could be susceptible to heat during prolonged energization. This factor should be considered when using fluids like water-glycol mixtures that degrade at higher temperatures. For manual operation, the DMDALPV648 comes equipped with a detent mechanism intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. Users should note that cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids and should avoid exposure to petroleum-based substances to prevent seal damage. This model also benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Additionally, it offers interchangeable coils compatible with other Sun Series 1 solenoid products and can handle up to 12 gpm (45 L/min) capacity at maximum operating pressures of 5000 psi (350 bar). Typical response times are around 50 ms, and it supports switching frequencies up to 15,000 cycles per hour. The manual override requires minimal force and has a short stroke length for ease of use during temporary adjustments.

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.
