The Sun Hydraulics DMDALRV548 (DMDALRV548) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This model is particularly noted for its robust construction, featuring a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). The valve is engineered with closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The DMDALRV548 operates without requiring a minimum hydraulic pressure, enhancing its versatility in various hydraulic systems. It includes manual override options with a detent mechanism designed for temporary actuation, supporting a mechanical life expectancy of about 7,000 cycles. The valve's compatibility with EPDM seals makes it suitable for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. Featuring a wet armature design, the DMDALRV548 allows the working fluid to surround the armature which helps in heat management during prolonged energization periods. This model also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it incorporates Sun\u2019s floating style construction to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. This valve supports up to 12 gpm (45 L/min) capacity and offers quick response times typically around 50 ms. It ensures minimal leakage at high pressures and is capable of handling up to 15,000 switching cycles per hour. The manual override features are user-friendly requiring minimal force and stroke. With its compact design weighing just 0.60 lb (0.30 kg), this valve offers an efficient solution for directional control in sophisticated hydraulic systems.

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.
