The Sun Hydraulics DMDAMRV248 (DMDAMRV248) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered for robust operation with a fatigue rating suitable for up to 5000 psi (350 bar) service. The unique design features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is not the primary concern. The DMDAMRV248 operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It incorporates a wet armature design whereby the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization. This valve is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based products to prevent damage. Additional features include interchangeable coils with other Sun Series 1 solenoid products and a manual override mechanism designed primarily for temporary actuation with an expected mechanical life of about 7,000 cycles. The valve supports up to 12 gpm (45 L/min) flow capacity and offers quick response times typically around 50 ms. Installation is facilitated by its floating style construction which minimizes internal parts binding due to variations in cavity or cartridge machining. This model also features a manual override that requires minimal force and allows precise control adjustments. With its compact size and lightweight design (0.60 lb/0.30 kg), the DMDAMRV248 provides a reliable solution for advanced hydraulic system configurations demanding high switching frequency and stringent leakage control.

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.
