The Sun Hydraulics DMDADBV4E12V (DMDADBV4E12V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is notable for its closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times, ideal for use as pilot controls where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it versatile across various operational scenarios. Constructed to handle a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), the DMDADBV4E12V ensures reliability even under demanding conditions. It features an innovative wet armature design where the working fluid surrounds the armature, which may need consideration regarding the type of fluid used due to potential heat exposure during prolonged coil energization. Suitable fluids include phosphate ester fluids when configured with EPDM seals; however, these seals are vulnerable to damage by petroleum-based substances. Additionally, this model incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and boasts a manual override feature with a mechanical life expectancy of around 7,000 cycles. The construction leverages Sun's floating style to minimize internal part binding caused by excessive installation torque or cavity/cartridge machining variations. This design consideration significantly contributes to the durability and longevity of the valve in industrial applications. The DMDADBV4E12V also features quick response times (typically around 50 ms), minimal valve leakage at higher pressures, and supports up to 15,000 switching cycles per hour, confirming its capability for high-frequency operation. Its compact size (.60 lb weight) and manual override functionality make it an efficient choice for systems requiring precise control with dependable manual intervention options.

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.
