The Sun Hydraulics DMDALAV912 (DMDALAV912) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for rigorous service conditions. The valve's spools B and R maintain a closed transition between two positions, optimizing performance by ensuring faster and more consistent response times especially when used as pilot controls. Equipped with EPDM seals, the DMDALAV912 is specifically configured for use with phosphate ester fluids, while exposure to petroleum-based fluids should be avoided to prevent seal damage. The wet armature design of the valve allows the working fluid to surround the armature, which could lead to fluid breakdown if the coil remains energized over extended periods. This model also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, this model incorporates Sun\u2019s floating style construction which minimizes internal parts binding that could result from excessive 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 a switching frequency of up to 15000 cycles per hour. The manual override feature requires a force of approximately 5 lbs at 1000 psi per port for actuation and has a stroke length of .10 inches (2.5 mm). The overall weight of the valve is .60 lb (0.30 kg).

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.
