The Sun Hydraulics DMDATBV298 (DMDATBV298) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and precise hydraulic control. Engineered with a balanced spool directional valve mechanism, it features a direct-acting operation that does not require minimum hydraulic pressure, enhancing its responsiveness and reliability in various applications. The valve's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure environments. This model incorporates closed transitions between Spools B and R, optimizing performance by ensuring faster and more consistent response times, particularly beneficial when used as pilot controls. It includes a wet armature design where the working fluid surrounds the armature, an essential feature for managing heat during prolonged coil energization. This design consideration is crucial for applications involving water-glycol mixtures which could degrade under high temperatures. The DMDATBV298 also offers flexibility in maintenance and compatibility; its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different system configurations. Additionally, the manual override feature is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based substances. The valve's construction also minimizes internal parts binding through its floating style design, accommodating variations in installation torque and machining. Overall, the DMDATBV298 provides a robust solution for demanding hydraulic applications requiring precise control and reliable operation under varying pressure conditions. Its technical specifications include a maximum capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar).

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.
