The Sun Hydraulics DMDALRN914N (DMDALRN914N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for efficient directional control in hydraulic systems. This direct-acting, balanced spool valve is uniquely constructed to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for high-pressure applications. The valve features a fatigue-rated solenoid tube assembly, ensuring durability and reliability under demanding conditions. Notably, the DMDALRN914N model incorporates closed transitions between Spools B and R, which enhances performance by providing faster and more consistent response times, ideal for pilot controls where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, facilitating versatile usage across various hydraulic setups. Additionally, it includes manual override options with a detent mechanism designed for temporary actuation; these manual controls (D or L control types) are rated for approximately 7,000 cycles. The cartridge uses EPDM seals configured for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. A wet armature design characterizes this model where the working fluid surrounds the armature\u2014important to consider if the coil remains energized over extended periods due to potential breakdowns in certain fluid types like water-glycol mixtures. Interchangeability of coils with other Sun Series 1 solenoid products adds to its flexibility in installation and maintenance. Furthermore, Sun's floating style construction minimizes internal parts binding that might occur due to excessive installation torque or variations in cavity/cartridge machining. With its robust design and versatile features, the DMDALRN914N is engineered to meet rigorous industrial demands while ensuring operational efficiency and reliability.

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.
