The Sun Hydraulics DMDALPN4E12V (DMDALPN4E12V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic control. This direct-acting, balanced spool directional valve operates with no minimum hydraulic pressure required, ensuring reliable functionality in various applications. The valve features a solenoid tube assembly rated for 5000 psi (350 bar), making it suitable for high-pressure environments. The DMDALPN4E12V incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times when used as pilot controls. This feature is particularly useful in applications where rapid switching and exact control are necessary. The manual override option, equipped with a detent mechanism, is intended for temporary actuation and supports up to 7,000 cycles, emphasizing the durability of the manual control components. This model utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals should not be exposed to petroleum-based fluids as they can cause damage. Additionally, the wet armature design of the valve allows the working fluid to surround the armature which could be a consideration if the coil remains energized for extended periods due to potential breakdowns in certain fluids. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and replacement processes. The floating style construction used in this model minimizes internal binding risks caused by excessive installation torque or variations in cavity/cartridge machining. With specifications like a flow capacity of 12 gpm (45 L/min) and fast response time typically around 50 ms, along with a switching frequency of up to 15,000 cycles/hr., the DMDALPN4E12V is engineered to meet rigorous demands of controlled hydraulic systems efficiently and reliably.

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.
