The Sun Hydraulics DNDAMYN (DNDAMYN) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This valve operates efficiently without requiring minimum hydraulic pressure, making it versatile for various applications. The solenoid tube assembly is rated for fatigue at a service pressure of 5000 psi or 350 bar, ensuring robust performance under demanding conditions. It offers multiple manual override options, though manual override functionality is not compatible with weatherized coils. For models with D or L control, the manual override's detent mechanism is intended for temporary actuation and has a mechanical life expectancy of around 7,000 cycles. This cartridge valve incorporates EPDM seals suitable for systems using phosphate ester fluids but advises against exposure to petroleum-based substances as they can damage the seals. The wet armature design allows the working fluid to surround the armature, which may become a concern if the coil remains energized for extended periods due to potential varnish formation in certain fluids like water-glycol mixtures. The product supports various coil termination and voltage options with or without surge protection. Its unique magnetic design enhances efficiency by providing high spool actuating force per watt expended, ensuring reliable 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 for enhanced durability in harsh environments. The DNDAMYN valve features Sun's floating style construction to minimize internal part binding caused by excessive installation torque or cavity/cartridge machining variations. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The valve's typical response time is approximately 50 ms, supporting high switching frequencies of up to 15,000 cycles per hour.

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.
