The Sun Hydraulics DMDADRV248 (DMDADRV248) is a solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a robust construction with the solenoid tube assembly being fatigue rated for high-pressure service, ensuring durability and reliability under demanding conditions. The DMDADRV248 valve incorporates closed transitions between spool positions B and R, which enhances performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. The manual override feature in models equipped with D or L control utilizes a detent mechanism intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. Designed with versatility in mind, the valve's cartridges configured with EPDM seals are suitable for systems using phosphate ester fluids. However, they should not be exposed to petroleum-based fluids as this could damage the seals. The wet armature design of the valve allows the working fluid to surround the armature, which can be critical if the coil remains energized over extended periods since some fluids may degrade at higher temperatures. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. It also features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. This design consideration ensures smoother operation and extends the operational lifespan of the cartridge.

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.
