The Sun Hydraulics DMDALBV712N (DMDALBV712N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic control applications. This direct-acting, balanced spool directional valve ensures precise control and reliable operation with its fatigue-rated solenoid tube assembly for pressures up to 5000 psi (350 bar). Notably, the valve features closed transitions between Spools B and R positions, optimizing performance by providing faster and more consistent response times particularly in pilot control applications where capacity is less critical. The DMDALBV712N operates effectively without minimum hydraulic pressure and incorporates a manual override with a detent mechanism designed for temporary actuation, supporting a mechanical life expectancy of around 7,000 cycles. It is compatible with EPDM seals suited for phosphate ester fluids; however, it should not be exposed to petroleum-based fluids which can damage the seals. The wet armature design of the valve allows the working fluid to surround the armature, potentially affecting fluid integrity under prolonged energization. This model also features interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Its construction includes Sun's floating style design which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at 110 SUS (24 cSt) capped at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The unit's manual override requires a force of about 5 lbs per 1000 psi on Port 1 and has a stroke length of .10 in (2.5 mm), making it both robust and user-friendly for various hydraulic system applications.

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.
