The Sun Hydraulics DMDAMAV612 (DMDAMAV612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that offers precise and reliable control in hydraulic systems. It features a direct-acting, balanced spool design that ensures operation without the need for minimum hydraulic pressure. The valve operates with a maximum capacity of 12 gpm/45 L/min and can handle pressures up to 5000 psi/350 bar, making it suitable for a variety of demanding applications. This model employs a fatigue-rated solenoid tube assembly designed for service at pressures up to 5000 psi/350 bar, which enhances its durability and lifespan under high-pressure conditions. The spools B and R maintain a closed transition between positions to optimize performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. The DMDAMAV612 incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature ensures smoother operation and increased reliability. Additionally, the valve's wet armature design allows the working fluid to surround the armature, aiding in heat management but requiring consideration of fluid type to avoid breakdown and varnish formation. With interchangeable coils compatible with other Sun Series 1 solenoid products, this model offers flexibility in maintenance and replacement. It also includes manual override capabilities with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles mechanically. This cartridge valve is equipped with EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based fluids which could damage the seals. Overall, the Sun Hydraulics DMDAMAV612 provides robust performance with versatile features suited for various hydraulic applications requiring precise 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.
