The Sun Hydraulics DMDAMAV812N (DMDAMAV812N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. With a direct-acting, balanced spool directional control mechanism, this valve excels in environments where precise fluid control is required. The valve features a fatigue rating for up to 5000 psi (350 bar), making it suitable for high-pressure applications. The DMDAMAV812N model ensures reliable operation with no minimum hydraulic pressure needed for activation. Its design includes closed transitions between spools B and R, optimizing performance by allowing faster and more consistent response times, particularly beneficial in pilot control setups where flow capacity is less critical. Additionally, the valve incorporates a wet armature design; thus, the working fluid not only lubricates but also cools the armature, mitigating the risk of overheating during prolonged coil energization. This model is compatible with EPDM seals specifically configured for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. For manual override operations, the valve features a detent mechanism designed to support temporary actuation with a mechanical life expectancy of about 7,000 cycles. The interchangeable coils of the DMDAMAV812N are consistent with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. Furthermore, Sun\u2019s floating style construction is utilized in this model to minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With specifications such as a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve ensures efficient and effective performance across various hydraulic functions. The robust construction and thoughtful engineering make the Sun Hydraulics DMDAMAV812N an ideal choice for demanding hydraulic systems requiring reliable directional control.

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.
