The Sun Hydraulics DMDADAN712 (DMDADAN712) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). It features a robust design with a solenoid tube assembly that is fatigue rated for demanding applications. The valve's spools B and R remain closed during the transition between the two positions, enhancing performance by providing faster and more consistent response times, particularly in pilot control applications where capacity is not a critical factor. This model includes an optional manual override with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy of approximately 7,000 cycles. It utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. The wet armature design of this valve ensures that the working fluid surrounds the armature, which is beneficial for heat dissipation but requires consideration of fluid type due to potential breakdown at high temperatures. Additionally, the DMDADAN712 valve incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun's floating style construction which minimizes internal parts binding. This construction aids in accommodating variations in installation torque and cavity/cartridge machining differences. Ideal for various hydraulic applications requiring reliable directional control and rapid response times, this valve exemplifies advanced engineering tailored for efficient hydraulic system management.

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.
