The Sun Hydraulics DNDAMZN728 (DNDAMZN728) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This versatile valve is engineered for high-performance applications with its solenoid tube assembly fatigue-rated for service up to 5000 psi (350 bar). Notably, it requires no minimum hydraulic pressure for operation, making it highly adaptable across various systems. The cartridge offers several manual override options, although models with manual controls like the D or L control are intended for temporary actuation only. These controls have a mechanical life expectancy of approximately 7,000 cycles. The valve incorporates EPDM seals suitable for phosphate ester fluid systems; however, exposure to petroleum-based fluids will damage these seals. Its wet armature design allows working fluid to surround the armature, which can lead to heat exposure from the coil if energized for extended periods\u2014potentially affecting certain fluids like water-glycol mixtures over time. Efficiency is a hallmark of this solenoid valve due to its unique magnetic design that provides high spool actuating force per watt expended. It includes interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction. With coil connector options rated up to IP69K and additional weatherized kits available, it offers robust environmental protection. Key specifications include a cavity T-31A series with a capacity of 10 gpm (40 L/min), response time typically around 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being 10 in/min at 3000 psi (160 cc/min at 210 bar). The switching frequency is an impressive 15,000 cycles per hour. The valve's construction minimizes internal binding risks due to excessive 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.
