The Sun Hydraulics DMDALBN212N (DMDALBN212N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting, balanced spool directional control. With a robust construction that includes a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, this valve ensures reliable operation under demanding conditions. The DMDALBN212N features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. This valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It incorporates manual override options with detent mechanisms designed for temporary actuation; these are particularly useful in maintenance or emergency situations. The DMDALBN212N is equipped with EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based products to avoid damage. Additionally, the DMDALBN212N utilizes a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity if exposed to prolonged heat. Interchangeability of coils with other Sun Series 1 solenoid products provides flexibility in system design and maintenance. The valve also features Sun\u2019s floating style construction which minimizes internal part binding due to installation torque or machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). Switching frequency can reach up to 15000 cycles per hour. This model is an essential component for systems requiring precise control and reliability in hydraulic fluid direction and flow management.

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.
