The Sun Hydraulics DMDADBV948 (DMDADBV948) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This valve is particularly effective in applications requiring precise control and robust performance under high pressure conditions up to 5000 psi (350 bar). Its design features a fatigue-rated solenoid tube assembly, ensuring durability and reliability in demanding environments. The DMDADBV948 valve offers closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, which is crucial when used as pilot controls. This model does not require a minimum hydraulic pressure to operate, making it versatile across various hydraulic systems. Additionally, it features manual override options with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles. This valve is compatible with EPDM seals specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design of the valve helps in cooling but may affect fluid integrity if the coil remains energized over extended periods. The interchangeable coils with other Sun Series 1 solenoid products add to its flexibility in usage. Other technical specifications include a flow capacity of up to 12 gpm (45 L/min), typical response times of 50 ms, and maximum leakage at 5 in\u00b3/min at 3000 psi. It also supports switching frequencies of up to 15,000 cycles/hr. The manual override requires minimal force, and the valve's construction incorporates Sun's floating style to minimize internal binding risks due to installation variances or cavity/cartridge machining differences.

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.
