The Sun Hydraulics DMDATAV548 (DMDATAV548) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve features a unique design with spools B and R that are closed during the transition between positions, enhancing performance by providing faster and more consistent response times, especially suitable for pilot controls where capacity is less critical. The DMDATAV548 incorporates a wet armature design which allows the working fluid to surround the armature, mitigating the risk of overheating during prolonged energization. However, it's important to note that fluids like water-glycol mixtures may degrade at high temperatures, affecting valve functionality. The valve is equipped with EPDM seals making it compatible with phosphate ester fluids but unsuitable for exposure to petroleum-based substances which could damage these seals. This model also features interchangeable coils that are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The manual override mechanism included in models with D or L control is designed for temporary actuation and has an expected mechanical life of approximately 7,000 cycles. Sun Hydraulics' DMDATAV548 is built using their floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This design detail ensures reliable operation and longevity even under demanding installation conditions. With a typical response time of 50 ms and a maximum leakage at 3000 psi rated at 5 in\u00b3/min., this valve is an optimal choice for systems requiring precise control with durable components.

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.
