The Sun Hydraulics DMDALBN914 (DMDALBN914) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for use in hydraulic systems where reliable control of fluid flow direction is necessary. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), it suits various demanding applications. The DMDALBN914 features closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The valve operates without minimum hydraulic pressure, adding to its versatility in different system conditions. This model includes a manual override with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. It uses EPDM seals suitable for phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. Additionally, the DMDALBN914 employs a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized for extended periods as it can lead to fluid breakdown at elevated temperatures. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. The construction incorporates Sun\u2019s floating style to minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature ensures prolonged operational integrity and reliability under varied mechanical installation 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.
