The Sun Hydraulics DMDAXPN248 (DMDAXPN248) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is well-suited for applications requiring precise control and robust performance. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it ideal for demanding hydraulic systems. The valve's design incorporates closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times in pilot control applications where capacity is less critical. Additionally, the DMDAXPN248 requires no minimum hydraulic pressure for operation, allowing for flexible integration into various system configurations. Equipped with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design of the valve helps in heat management around the coil but requires consideration regarding fluid compatibility and operational durations to prevent breakdowns. For maintenance or manual operation, the valve includes a detent mechanism in its manual override feature and offers a mechanical life expectancy of about 7,000 cycles. Coils used in this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. This cartridge also benefits from Sun\u2019s floating style construction which minimizes internal part binding caused by excessive installation torque or machining variations in cavity/cartridge setups. With a maximum capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, the DMDAXPN248 is an efficient solution designed to enhance system 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.
