The Sun Hydraulics DMDALAN212N (DMDALAN212N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to deliver efficient control in hydraulic systems. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring durability and reliability under high-pressure conditions. The valve's spools B and R are closed during the transition between positions, enhancing performance by providing faster and more consistent response times, especially when utilized as pilot controls. The DMDALAN212N requires no minimum hydraulic pressure for operation due to its direct actuation design. This model includes a manual override with a detent mechanism intended for temporary actuation; this feature has a mechanical life expectancy of around 7,000 cycles. The valve is equipped with EPDM seals optimized for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based substances as they can cause damage. With a wet armature design, the valve's working fluid surrounds the armature which may be subject to heat during prolonged coil energization\u2014important to consider in applications involving heat-sensitive fluids. The interchangeable coils compatible with other Sun Series 1 solenoid products add versatility in usage and maintenance. Moreover, Sun\u2019s floating style construction incorporated into the valve minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. This model supports flow capacities up to 12 gpm (45 L/min) and can handle switching frequencies of up to 15,000 cycles per hour. Its robust construction and thoughtful design elements make it suitable for demanding applications requiring precise fluid control with reliable performance.

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.
