The Sun Hydraulics DMDALPN612 (DMDALPN612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a robust solenoid tube assembly that is fatigue rated for demanding applications, ensuring reliable operation under high-pressure conditions. The DMDALPN612 valve offers closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The absence of minimum hydraulic pressure requirements for operation allows this valve to function effectively in various system configurations without the need for additional pressure support. Equipped with EPDM seals, the DMDALPN612 is compatible with phosphate ester fluids, although it should not be exposed to petroleum-based fluids which can damage the seals. Its wet armature design allows the working fluid to cool the armature, although prolonged energization should be managed carefully to prevent fluid degradation. This model also supports interchangeable coils with other Sun Series 1 solenoid products and includes manual override capabilities with a detent mechanism designed for temporary actuation. The manual control assembly promises a mechanical life expectancy of approximately 7,000 cycles. Additionally, the valve incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations. This makes the DMDALPN612 an adaptable solution suited to various industrial hydraulic applications requiring precise control 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.
