The Sun Hydraulics DMDADRV2E12V (DMDADRV2E12V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve is notable for its robust construction and precision operation. Engineered to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), it is an ideal choice for systems requiring reliable directional control. The valve features a unique closed transition between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The solenoid tube assembly of the DMDADRV2E12V is fatigue rated, making it suitable for high-pressure scenarios without compromising durability. For operational flexibility, this model can be equipped with either D or L manual controls, incorporating a detent mechanism designed primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Additionally, the valve's wet armature design allows the working fluid to surround the armature, which helps in heat dissipation but requires careful selection of fluid to avoid breakdowns at elevated temperatures. This cartridge also features interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. Designed with EPDM seals specifically for use with phosphate ester fluids, it ensures that exposure to incompatible materials like petroleum-based fluids does not compromise seal integrity. With its comprehensive design considerations and built-in versatility, the Sun Hydraulics DMDADRV2E12V valve stands out as a reliable component suited for advanced hydraulic systems demanding precise control and long-term reliability.

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.
