The Sun Hydraulics DMDATPV548 (DMDATPV548) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate seamlessly without requiring a minimum hydraulic pressure. It features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring durability and reliability even under high-pressure conditions. The valve's spools\u2014B and R\u2014are closed in the transition between their two positions, enhancing performance limits while sacrificing some capacity. This model is particularly effective when used as pilot controls thanks to its closed transition design that offers faster and more consistent response times. The manual override in models equipped with the D or L control utilizes a detent mechanism intended for temporary actuation, with an expected mechanical life of approximately 7,000 cycles. It is crucial to note that cartridges configured with EPDM seals are suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The DMDATPV548 incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting performance if the coil remains energized for extended periods due to heat exposure. Additionally, this model uses interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun's floating style construction which minimizes internal part binding caused by excessive installation torque or cavity/cartridge machining variations. This valve supports a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 50 ms, making it an efficient choice for various hydraulic applications requiring robust control and swift action.

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.
