The Sun Hydraulics DMDALPN211 (DMDALPN211) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to function efficiently without minimum hydraulic pressure, making it suitable for a wide range of applications. It features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring durability and reliability in demanding environments. The DMDALPN211 valve incorporates closed transitions between positions B and R, optimizing performance by providing faster and more consistent response times, particularly useful in pilot control setups where capacity is not a primary concern. The manual override options (D or L control) include a detent mechanism intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Designed with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Additionally, the valve uses a wet armature design which involves the working fluid surrounding the armature\u2014this can lead to breakdowns in certain fluids like water-glycol mixtures under prolonged energization. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing coils to be mounted in either direction on the tube. The construction also features Sun's floating style which minimizes internal parts binding caused by installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 5 in\u00b3/min at 3000 psi. The switching frequency can reach up to 15,000 cycles/hr, making the DMDALPN211 an effective solution for various hydraulic control applications requiring high precision 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.
