The Sun Hydraulics DMDAMNN812N (DMDAMNN812N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its versatility in various applications. Featuring a robust design, the solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring reliability and durability in demanding environments. With spools B and R closed during the transition between positions, the DMDAMNN812N offers superior performance by providing faster and more consistent response times, particularly when used as pilot controls. This design choice optimizes the valve for applications where capacity is less critical but speed and precision are paramount. The valve also incorporates a wet armature design; thus, it is important to consider the type of fluid used, as some fluids may degrade at higher temperatures influenced by prolonged coil energization. This model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube to accommodate different installation requirements. It also features Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The DMDAMNN812N has a maximum flow capacity of 12 gpm (45 L/min) and can handle pressures up to 5000 psi (350 bar). It also boasts quick response times typically around 50 ms and allows for manual override with a force requirement of approximately 5 lbs at 1000 psi for Port 1. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based fluids.

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.
