The Sun Hydraulics DMDAMNV612N (DMDAMNV612N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and offers a flow capacity of up to 12 gpm (45 L/min), making it suitable for various demanding hydraulic applications. The response time of the valve is typically around 50 ms, ensuring quick and efficient operations. With its robust construction, the DMDAMNV612N incorporates Sun's floating style construction which helps in minimizing internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This design enhancement significantly enhances the reliability and performance of the valve under diverse operating conditions. The valve features interchangeable coils with other Sun Series 1 solenoid products, allowing for flexible installation options as coils can be mounted on the tube in either direction. The wet armature design of the valve ensures that the working fluid surrounds the armature, which is crucial in applications where coil heat could affect performance. However, it's important to note that certain fluids like water-glycol mixtures may degrade at higher temperatures influenced by prolonged coil energization. Additionally, this model is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. For manual override operations, this model includes a detent mechanism designed for temporary actuation with an estimated mechanical life expectancy of approximately 7,000 cycles. Overall, the Sun Hydraulics DMDAMNV612N offers exceptional durability and performance for hydraulic systems requiring reliable directional control and fast response times.

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.
