The Sun Hydraulics DMDALBV212 (DMDALBV212) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. This direct-acting, balanced spool directional valve is engineered to operate with no minimum hydraulic pressure required, making it highly effective in a variety of settings. The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for use as pilot controls where capacity is less critical. The DMDALBV212 boasts a robust construction with a fatigue rating for up to 5000 psi (350 bar) service, making it suitable for high-pressure applications. It includes an interchangeable solenoid tube assembly compatible with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different system configurations. The wet armature design of the valve ensures that the working fluid surrounds the armature which helps manage the heat generated by the coil but requires consideration of fluid type to avoid breakdown and varnish formation. Manual override options are available with detent mechanisms designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based fluids. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, this valve supports efficient operation and control. Additionally, it incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This design detail ensures reliable performance even under varied installation 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.
