The Sun Hydraulics DMDAMBN948 (DMDAMBN948) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly suitable for 5000 psi (350 bar) service, ensuring durability and reliability even under high-stress conditions. The valve's design includes closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times at the cost of lower flow capacity \u2013 an ideal setup when used as pilot controls where capacity is less critical. This model is equipped with EPDM seals specifically configured for use with phosphate ester fluids, which are necessary to avoid damage from petroleum-based substances. Its wet armature design allows the working fluid to cool the armature directly but requires consideration of fluid selection to prevent breakdowns from prolonged heat exposure. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and setup. Moreover, the valve incorporates Sun\u2019s floating style construction that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), this valve is engineered for precision and efficiency in hydraulic systems requiring meticulous control. Additional features include a manual override mechanism with an expected mechanical life of about 7,000 cycles and minimal manual force requirements for operation, enhancing both usability and longevity.

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.
