The Sun Hydraulics DMDAMNV912 (DMDAMNV912) is a solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This model is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a rated flow capacity of 12 gpm (45 L/min). It is notable for its robust construction, including a solenoid tube assembly that is fatigue rated for high-pressure service. The DMDAMNV912 offers precise control with closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times ideal for applications requiring precise pilot controls. This valve is also equipped with an interchangeable coil system compatible with other Sun Series 1 solenoid products, allowing for flexible installation orientations. The wet armature design surrounds the armature with the working fluid, which helps in heat management but requires careful selection of fluid types to avoid breakdowns or varnish formation. Additionally, the valve features Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations. For manual override operations, the DMDAMNV912 includes a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. The manual override requires a force of approximately 5 lbs at 1000 psi per port and has a stroke length of .10 inches. The overall durability and reliability of this model are further supported by its design specifications including a typical response time of 50 ms and maximum valve leakage at 110 SUS (24 cSt) maintained at around 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). This makes the DMDAMNV912 an excellent choice for various hydraulic applications requiring reliable directional control and swift actuation.

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.
