The Sun Hydraulics DMDAMRV712 (DMDAMRV712) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 50 ms. With a flow capacity of up to 12 gpm (45 L/min), it meets the demands of various hydraulic applications requiring precise control and reliability. The valve features closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDAMRV712 is equipped with manual override options including the D or L control, which are designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Special attention is given to its construction; the valve uses EPDM seals suitable for phosphate ester fluids but should avoid contact with petroleum-based fluids that could damage the seals. Additionally, its wet armature design allows the working fluid to surround the armature, which could affect fluid integrity if exposed to prolonged heat. Interchangeability is another key feature; coils used in this model are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The design also incorporates Sun's floating style construction which minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. This model's robust design also includes features such as a maximum switching frequency of 15,000 cycles/hr and minimal valve leakage at high pressures, ensuring efficient operation and longevity in demanding hydraulic environments.

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.
