The Sun Hydraulics DNDAMUN4E12V (DNDAMUN4E12V) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. The solenoid tube assembly is built to withstand up to 5000 psi (350 bar), ensuring robust performance for demanding applications. This valve operates without the need for minimum hydraulic pressure, making it versatile in various fluid power systems. It offers several manual override options, although these are incompatible with weatherized coils. Notably, models with D or L control have a detent mechanism intended for temporary actuation with a life expectancy of approximately 7,000 cycles. The valve is equipped with EPDM seals suitable for phosphate ester fluids but may degrade if exposed to petroleum-based substances. Utilizing a wet armature design, the armature is immersed in working fluid which can affect performance if the coil is energized continuously due to heat exposure. A broad range of coil termination and voltage options are available, enhancing customization and functionality. The high-efficiency solenoid design ensures reliable shifting and high spool actuating force per watt expended. This model incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or cavity machining variations. It fits into a T-31A cavity and belongs to Series 1 with a capacity of 10 gpm (40 L/min). Its maximum operating pressure is 5000 psi (350 bar), and it provides quick response times typically around 50 ms. The valve leakage at maximum specified conditions is minimal at 10 in\u00b3/min (160 cc/min). With interchangeable coils compatible across Sun Series 1 products and IP69K-rated connector options, this valve offers extensive environmental protection capabilities.

This solenoid-operated 4-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.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- 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 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.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- 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.
