The Sun Hydraulics DMDALAN548 (DMDALAN548) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control in hydraulic systems. This model is engineered to be fatigue rated for demanding 5000 psi (350 bar) service conditions. It features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial when utilized as pilot controls. The DMDALAN548 requires no minimum hydraulic pressure to operate, making it versatile for various applications. It includes manual override options with a detent mechanism designed for temporary actuation, suitable for applications requiring manual intervention. The mechanical life expectancy of the manual control assembly in this model is approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended; however, they must avoid exposure to petroleum-based fluids which can damage the seals. The design incorporates a wet armature setup where the working fluid surrounds the armature\u2014a consideration when dealing with prolonged coil energization as it can lead to fluid breakdown and varnish formation affecting cartridge functionality. This model also boasts interchangeable coils with other Sun Series 1 solenoid products and features Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, this valve is an efficient choice for a variety of hydraulic applications needing reliable directional 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.
