The Sun Hydraulics DMDAMAV548 (DMDAMAV548) is a solenoid-operated 3-way, 2-position cartridge valve, designed for high-performance hydraulic systems. It features a direct-acting, balanced spool directional valve mechanism that ensures reliable operation without the need for minimum hydraulic pressure. The valve is particularly noted for its closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times, which are crucial when the valve is used as pilot controls. This model incorporates a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar), making it suitable for rigorous applications. It also benefits from a wet armature design where the working fluid surrounds the armature, critical in managing heat dissipation during prolonged coil energization. This design consideration is essential when using fluids like water-glycol mixtures that are susceptible to breakdown and varnish formation at high temperatures. For maintenance or manual operation, the DMDAMAV548 features a detent mechanism in its manual override which is intended for temporary actuation with an expected mechanical life of about 7,000 cycles. The cartridge also supports easy interchangeability of coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction of this valve minimizes internal part binding due to installation torque or cavity/cartridge machining variations through Sun's floating style design. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, this valve ensures efficient fluid control in various hydraulic setups. Additionally, it offers compatibility with EPDM seals specifically for phosphate ester fluids while cautioning against exposure to petroleum-based substances which could damage these seals.

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.
