The Sun Hydraulics DMDADPV812N (DMDADPV812N) is a solenoid-operated 3-way, 2-position cartridge valve designed to be a direct-acting, balanced spool directional valve. It features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), ensuring reliability and performance under high-pressure conditions. This model is particularly noted for its closed transition between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDADPV812N operates without needing a minimum hydraulic pressure, enhancing its versatility across various applications. Additionally, it includes manual override options with the D or L control featuring a detent mechanism designed primarily for temporary actuation. The mechanical life expectancy of this manual control assembly is approximately 7,000 cycles. This valve uses EPDM seals suited for systems that utilize phosphate ester fluids, while caution is advised against exposure to petroleum-based fluids which can damage these seals. The wet armature design of the valve means that the working fluid surrounds the armature, potentially affecting fluid integrity if subjected to prolonged heat exposure from the coil. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility and ease of use of this valve. It also incorporates Sun's floating style construction which minimizes internal part binding due to variations in installation torque or cavity/cartridge machining discrepancies. With a maximum operating capacity of 12 gpm (45 L/min) and quick response time typically around 50 ms, the DMDADPV812N offers an effective solution for controlling flow in 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.
