The Sun Hydraulics DMDALBV712 (DMDALBV712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without requiring minimum hydraulic pressure, making it versatile for various applications. It features a robust design with a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability in demanding environments. The valve's spools, B and R, are closed during the transition between positions to enhance performance limits at the cost of lower capacity. However, this closed transition facilitates faster and more consistent response times when used as pilot controls. The DMDALBV712 incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization. This model supports manual override with a detent mechanism intended for temporary actuation, boasting a mechanical life expectancy of about 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. Additionally, the DMDALBV712 can accommodate interchangeable coils from other Sun Series 1 solenoid products and features Sun's floating style construction to minimize internal parts binding due to installation variances. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms, this valve is suitable for high-frequency operations reaching up to 15,000 cycles per hour. Its compact size and manual override features make it an efficient choice for sophisticated hydraulic systems requiring reliable 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.
