The Sun Hydraulics DMDATBV948 (DMDATBV948) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its responsiveness and reliability across various applications. The DMDATBV948 features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring durability under high-pressure conditions. This model is particularly noted for its closed transition between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The valve incorporates a wet armature design, which means the working fluid surrounds the armature; this is an important consideration as prolonged energization can lead to fluid degradation at high temperatures. Interchangeable coils with other Sun Series 1 solenoid products add versatility to this model, allowing for easy maintenance and replacement. It also features Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi and a flow capacity of 12 gpm (45 L/min), the DMDATBV948 provides robust performance for demanding applications. Additional features include a manual override option with a mechanical life expectancy of around 7,000 cycles and EPDM seals suitable for phosphate ester fluids. Overall, the Sun Hydraulics DMDATBV948 valve offers reliable performance with enhanced operational flexibility suited for various hydraulic system applications requiring precise directional control and high-pressure operation.

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.
