The Sun Hydraulics DMDADBN948 (DMDADBN948) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for robust and precise hydraulic control. Engineered with a direct-acting, balanced spool mechanism, this valve ensures reliable operation without the need for minimum hydraulic pressure. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), making it ideal for demanding applications. The valve's design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. The manual override options (D or L control) are equipped with a detent mechanism designed primarily for temporary actuation, supporting about 7,000 mechanical life cycles. This model uses EPDM seals specifically for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. Its wet armature design allows the working fluid to surround the armature which may affect fluid integrity under prolonged energization. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this component, while its floating style construction minimizes internal parts binding due to installation variances or machining inconsistencies. The DMDADBN948 supports a maximum flow capacity of 12 gpm (45 L/min) and features quick response times typically around 50 ms. With its robust construction and precise engineering, the Sun Hydraulics DMDADBN948 is an essential component in advanced hydraulic systems requiring reliable directional control and rapid switching capabilities.

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.
