The Sun Hydraulics DMDAXBN814 (DMDAXBN814) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust service with a fatigue rating of 5000 psi (350 bar). It features a closed transition between Spools B and R, optimizing performance by providing faster and more consistent response times in applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, enhancing its versatility in various hydraulic systems. Equipped with an optional manual override (identified by control options D, L, and T), the DMDAXBN814 allows temporary manual actuation with a mechanical life expectancy of approximately 7,000 cycles. The wet armature design of the valve ensures that the working fluid surrounds the armature which may affect fluid integrity under prolonged energization. Notably, this model uses EPDM seals suited for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. This model supports a maximum flow capacity of 12 gpm (45 L/min) and can handle switching frequencies up to 15,000 cycles per hour. Coils used in this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. Additionally, the floating style construction minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. With its compact design featuring a solenoid tube diameter of .75 inches (19 mm) and light model weight of .60 lb (0.30 kg), the DMDAXBN814 offers an efficient solution for directing flow in hydraulic circuits where high performance and reliability are essential.

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.
