The Sun Hydraulics DMDADPN248 (DMDADPN248) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is specifically engineered 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 unique construction that includes a fatigue-rated solenoid tube assembly and interchangeable coils compatible with other Sun Series 1 solenoid products. The valve is characterized by its closed transition between positions B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The incorporation of the Sun floating style construction minimizes internal parts binding, ensuring reliable operation even under varying installation torques and machining variations. Additionally, the DMDADPN248 valve offers manual override options with a mechanical life expectancy of approximately 7,000 cycles for models equipped with D or L control. The wet armature design aids in cooling but requires careful selection of working fluids to prevent breakdowns from prolonged coil energization. Specific configurations with EPDM seals are intended for use with phosphate ester fluids to avoid damage from petroleum-based substances. This versatile valve also supports a typical response time of 50 ms and can handle switching frequencies up to 15,000 cycles per hour. Its robust design and precise engineering make it an optimal choice for demanding hydraulic applications requiring reliable directional control and rapid response capabilities.

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.
