The Sun Hydraulics DMDAMNN912 (DMDAMNN912) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve operates with no minimum hydraulic pressure requirement, enhancing its versatility in various system configurations. Equipped with B and R spools that are closed during transition, the DMDAMNN912 offers improved performance limits by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The manual override feature, available in models with D or L control, uses a detent mechanism designed for temporary actuation only and has a mechanical life expectancy of about 7,000 cycles. For compatibility with different fluid types, cartridges configured with EPDM seals are specifically used in systems containing phosphate ester fluids; however, they should not be exposed to petroleum-based fluids as this can damage the seals. The wet armature design of the valve allows the working fluid to surround the armature which might be a consideration if the coil remains energized for extended periods. Additionally, this model incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted on the tube in either direction. It also features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This design detail ensures reliable and consistent operation under varying installation conditions. With capabilities such as a maximum flow capacity of 12 gpm (45 L/min), quick response times typically around 50 ms, and switching frequency up to 15,000 cycles/hr, the Sun Hydraulics DMDAMNN912 valve is an effective solution for advanced hydraulic system controls requiring precise directionality and fluid handling 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.
