The Sun Hydraulics DMDADPV848 (DMDADPV848) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic system control. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, making it versatile for a wide range of applications. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring reliability under high-pressure conditions. The valve's design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The model comes with optional manual overrides (D, L, T controls), each with a mechanical life expectancy of approximately 7,000 cycles. Notably, the valve employs a wet armature design; thus, the working fluid surrounds the armature which can affect fluid integrity if exposed to high temperatures over prolonged periods. For compatibility with different system fluids, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; however, they must not be exposed to petroleum-based fluids as these will damage the seals. Additionally, this model offers interchangeable coils that align with other Sun Series 1 solenoid products and can be mounted in either direction for added installation flexibility. The DMDADPV848 also incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of up to 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve is an essential component for systems requiring precise control and durability.

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.
