The Sun Hydraulics DMDALBV2E12V (Material Number: DMDALBV2E12V) is a solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve is notable for its high-performance capabilities, particularly in applications requiring precise and rapid control of hydraulic flow. The valve features a fatigue rating for 5000 psi (350 bar) service, ensuring durability under high-pressure conditions. The DMDALBV2E12V incorporates a closed transition between Spools B and R, optimizing performance by providing faster and more consistent response times, which is ideal for pilot controls where capacity is less critical. The manual override options available with the D or L control have a mechanical life expectancy of about 7,000 cycles, suitable for temporary actuation needs. This model utilizes EPDM seals specifically designed for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of the valve helps in cooling but requires consideration regarding the type of fluid used because prolonged exposure to heat can degrade certain fluids. With an interchangeable coil system compatible with other Sun Series 1 solenoid products and a floating style construction that minimizes internal binding risks due to installation torque or machining variations, this valve offers flexibility and reliability in installation and operation. Additional specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), typical response time of 50 ms, and manual override features that require minimal force. These characteristics make the Sun Hydraulics DMDALBV2E12V an excellent choice for sophisticated hydraulic systems demanding high reliability and precise 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.
