The Sun Hydraulics DMDADRN4E12V (DMDADRN4E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without minimum hydraulic pressure and features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). Ideal for applications requiring robust performance such as in pilot controls, its closed transition between spools B and R ensures faster and more consistent response times at the expense of lower capacity. This model is equipped with manual override options including D or L control types, which are intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. It also incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The wet armature design allows the working fluid to surround the armature which could be significant when the coil is energized for extended periods. The valve supports a maximum flow capacity of 12 gpm (45 L/min) and features interchangeable coils with other Sun Series 1 solenoid products. Its construction includes Sun's floating style design which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. Additional technical specifications include a typical response time of 50 ms, maximum leakage at 3000 psi rated at 5 in\u00b3/min., and a switching frequency of up to 15,000 cycles/hr. The manual override requires a force of about 5 lbs at 1000 psi on port one and has a stroke length of .10 in (2.5 mm). The compact design weighs just .60 lb (0.30 kg), making it suitable for various installation environments while maintaining efficient operation and 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.
