The Sun Hydraulics DMDALBN714 (DMDALBN714) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional control mechanism. This model is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The DMDALBN714 offers quick response times with typical values around 50 ms, making it suitable for applications requiring fast and precise control. Key features include interchangeable coils with other Sun Series 1 solenoid products, allowing for flexible installation options. The valve's wet armature design ensures that the working fluid surrounds the armature, which is crucial in applications where the valve may be energized for extended periods. However, it\u2019s important to note that certain fluids like water-glycol mixtures may degrade at high temperatures. The manual override feature of this model, equipped with D or L control, is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. It also incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This valve uses EPDM seals intended for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. With its robust design and versatile performance characteristics, the DMDALBN714 is ideal for use as pilot controls in hydraulic systems where precision and reliability are paramount.

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.
