The Sun Hydraulics DMDADRN712 (DMDADRN712) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding applications. The spool transitions between positions B and R are closed, enhancing performance by providing faster and more consistent response times during pilot control operations, where flow capacity is less critical. This model does not require a minimum hydraulic pressure to operate and includes options for manual override controls (D, L, T), which are designed primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve's wet armature design allows the working fluid to surround the armature, which is crucial when the coil is energized for extended periods as it can lead to breakdown in certain types of fluids such as water-glycol mixtures. The DMDADRN712 can handle a flow capacity up to 12 gpm (45 L/min) and operates efficiently with maximum valve leakage at 110 SUS (24 cSt) being only 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). It also supports a high switching frequency of up to 15,000 cycles per hour. For ease of installation and maintenance, this valve features interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction to minimize internal parts binding. Additionally, the DMDADRN712 utilizes EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based fluids which can damage the seals. The manual override requires a force of approximately 5 lbs at 1000 psi on Port 1 and has a stroke length of .10 inches (2.5 mm). With its robust construction and versatile features, this valve is an excellent choice for various hydraulic control applications requiring precise flow direction management 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.
