The Sun Hydraulics DMDALRV912 (DMDALRV912) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is ideal for applications requiring precise control and reliability under high pressure conditions up to 5000 psi (350 bar). The DMDALRV912 features a fatigue-rated solenoid tube assembly and utilizes a wet armature design, where the working fluid surrounds the armature, enhancing durability but requiring consideration of fluid characteristics due to potential heat exposure. The valve offers closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. It operates without minimum hydraulic pressure, adding to its versatility in various system configurations. The model comes equipped with manual override options (D or L control), primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended, as exposure to petroleum-based fluids can damage these seals. Additionally, the DMDALRV912 supports interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun's floating style construction to minimize internal part binding due to installation stresses. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum switching frequency of 15,000 cycles per hour. This model also allows easy integration into existing setups with its standardized cavity (T11A) and common installation features like a .75 in (19 mm) solenoid tube diameter and an installation torque of 30-35 lbf-ft (41-47 Nm). The compact design weighs just .60 lb (0.30 kg), facilitating ease of handling and installation.

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.
