The Sun Hydraulics DMDALBN814 (DMDALBN814) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a fatigue-rated solenoid tube assembly suitable for demanding applications. The valve's spools B and R are closed during the transition between positions, which enhances performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. This model is equipped with manual override options including D or L control, with the detent mechanism intended for temporary actuation. The manual control assembly boasts a mechanical life expectancy of about 7,000 cycles. Additionally, the DMDALBN814 utilizes EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Another feature includes its wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization due to heat exposure. Coils for this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The design incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The DMDALBN814 offers robust construction and versatile application potential in hydraulic systems requiring precise control and reliability under high-pressure conditions.

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.
