The Sun Hydraulics DMDADRV4E12V (DMDADRV4E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic system management. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its versatility across a wide range of applications. Featuring a fatigue rating of 5000 psi (350 bar), the valve is built to withstand demanding operational conditions. The solenoid tube assembly's design ensures that spools B and R remain closed during the transition between positions, optimizing performance by providing faster and more consistent response times especially in pilot control applications. This model incorporates a wet armature design where the working fluid surrounds the armature. This setup aids in heat management but requires attention when energized for extended periods as some fluids may degrade under prolonged exposure to heat. Additionally, the DMDADRV4E12V features interchangeable coils with other Sun Series 1 solenoid products, offering flexibility and ease of maintenance by allowing mounting on the tube in either direction. The valve also boasts Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. It supports a maximum flow capacity of 12 gpm (45 L/min) and maintains swift response times typically around 50 ms. Its manual override mechanism is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. With its robust design and versatile features, the Sun Hydraulics DMDADRV4E12V valve is an excellent choice for ensuring reliable operation and precise control in hydraulic systems across various applications.

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.
