The Sun Hydraulics DMDAMNV912N (DMDAMNV912N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve is noted for its robust construction and reliable operation, suitable for applications requiring precise control of fluid direction. The valve operates with no minimum hydraulic pressure required, enhancing its versatility across various hydraulic applications. Featuring a fatigue-rated solenoid tube assembly designed to withstand pressures up to 5000 psi (350 bar), the DMDAMNV912N ensures durable performance under demanding conditions. The spools B and R maintain a closed transition between positions, optimizing the valve's performance by allowing faster and more consistent response times, particularly useful in pilot control settings where capacity is less critical. This model incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Additionally, the valve's wet armature design means that the working fluid surrounds the armature; this is an essential consideration as prolonged coil energization can lead to fluid degradation at high temperatures. The DMDAMNV912N supports a flow capacity of 12 gpm (45 L/min) and features interchangeable coils with other Sun Series 1 solenoid products, enhancing its adaptability for system integration. It also includes manual override capabilities with a detent mechanism intended for temporary actuation. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent seal damage from petroleum-based fluids. Overall, the Sun Hydraulics DMDAMNV912N offers reliable and efficient directional control in hydraulic systems, making it an excellent choice for various industrial applications requiring precise fluid management under high-pressure conditions.

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.
