The Sun Hydraulics DMDALAN712N (DMDALAN712N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, making it versatile for various applications. It features a robust design with a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), ensuring durability and reliability in demanding environments. The valve offers closed transitions between its two positions (Spools B and R), enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. Additionally, the model incorporates manual override options with a detent mechanism designed for temporary actuation. The manual control assembly (available in D, L, or T configurations) supports approximately 7,000 mechanical life cycles. For systems using phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design of the valve ensures that the working fluid surrounds the armature which may require consideration regarding heat exposure if the coil remains energized over extended periods. This model also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Its floating style construction minimizes internal part binding due to installation torque or machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity of 12 gpm (45 L/min), and typical response times of around 50 ms. The model\u2019s compact and efficient design makes it an excellent choice for a wide range of hydraulic control applications needing reliable directional control and rapid switching capabilities.

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.
