The Sun Hydraulics DMDAXRV548 (Material Number DMDAXRV548) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional control valve. This model features a fatigue-rated solenoid tube assembly designed for up to 5000 psi (350 bar), making it robust for high-pressure applications. The valve's performance is characterized by closed transitions between Spools B and R, enhancing performance limits at the cost of reduced capacity. However, in applications such as pilot controls where high capacity is not crucial, this feature enables faster and more consistent response times. The DMDAXRV548 does not require a minimum hydraulic pressure to operate, which allows it to function efficiently in various system conditions. The model may include manual override controls (D, L, or T types), which are intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended; these should not be exposed to petroleum-based fluids as they can degrade the seals. This valve also employs a wet armature design where the working fluid surrounds the armature; this aspect needs consideration regarding the type of fluid used due to potential breakdowns at high temperatures. Additionally, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time of about 50 ms. The valve is designed with Sun's floating style construction to minimize internal binding caused by installation stresses or machining variations in cavity/cartridge setups. This product is well-suited for applications requiring reliable directional control in hydraulic systems where robustness and precision are necessary.

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.
