The Sun Hydraulics DNDAMUN912 (DNDAMUN912) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. Engineered for robust performance, the solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring reliable service in demanding applications. This valve operates without the need for minimum hydraulic pressure, making it versatile for various systems. It offers multiple manual override options, although these are not compatible with weatherized coils. The manual controls have a mechanical life expectancy of approximately 7,000 cycles and are intended for temporary actuation. Notably, cartridges with EPDM seals are suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based substances to prevent seal damage. The valve employs a wet armature design, where the working fluid surrounds the armature and is subjected to heat from the coil. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade at elevated temperatures over time. The solenoid features a unique magnetic design that enhances efficiency by providing high spool actuating force per watt expended, contributing to dependable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options offer protection ratings up to IP69K, and additional weatherized coils and kits are available for enhanced environmental protection. With a cavity size of T-31A and a capacity of 10 gpm (40 L/min), this valve supports maximum operating pressures of up to 5000 psi (350 bar). It exhibits typical response times of around 50 ms and maintains maximum leakage rates at specified conditions. The Sun floating style construction minimizes internal binding risks due to installation torque or machining variations.

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.
