The Sun Hydraulics DMDALPV712N (DMDALPV712N) is a solenoid-operated 3-way, 2-position cartridge valve that exemplifies precision and durability in hydraulic systems control. This direct-acting, balanced spool directional valve is designed to operate without minimum hydraulic pressure, enhancing its responsiveness and ease of integration into various applications. It features a fatigue rating for 5000 psi (350 bar) service, ensuring reliability under high-pressure conditions. The DMDALPV712N valve boasts a quick response time of approximately 50 ms and can handle a flow capacity of up to 12 gpm (45 L/min), making it suitable for systems requiring rapid actuation. The manual override option equipped with detent mechanisms is intended for temporary actuation, providing an added layer of operational flexibility. Notably, the valve incorporates EPDM seals suitable for use with phosphate ester fluids, though these seals must not be exposed to petroleum-based fluids as they could degrade. A significant design aspect of the DMDALPV712N is its wet armature setup where the working fluid surrounds the armature; this design choice is crucial for applications where the coil may be energized continuously, although care must be taken with certain fluids that could deteriorate at higher temperatures. Additionally, its construction utilizes Sun's floating style which minimizes internal parts binding\u2014a common issue in valves due to installation torque or machining variations. Interchangeability of coils with other Sun Series 1 solenoid products adds to the versatility of this model, allowing users to adapt or upgrade their systems without extensive modifications. With a mechanical life expectancy of about 7,000 cycles for the manual control assembly and switching frequency capabilities up to 15,000 cycles per hour, the DMDALPV712N stands out as a robust solution for directing fluid flow in advanced hydraulic circuits.

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.
