The Sun Hydraulics DMDADPV248 (DMDADPV248) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, ensuring reliable functionality across a wide range of applications. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi or 350 bar service, making it robust for demanding environments. The valve's design incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times during operation. This characteristic is particularly beneficial when the valve is used as pilot controls where capacity isn't a primary concern. Additionally, the DMDADPV248 can be equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. This model also benefits from interchangeable coils with other Sun Series 1 solenoid products and features a wet armature design where the working fluid surrounds the armature. Special attention should be given if the coil remains energized for extended periods as this can lead to breakdown in certain fluid types. The manual override option in this valve includes a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. Sun Hydraulics has integrated their floating style construction into the DMDADPV248 to minimize internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. Overall, this valve offers a compact and efficient solution for various hydraulic control systems demanding high reliability and performance.

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.
