The Sun Hydraulics DNDAMZN648 (DNDAMZN648) is a solenoid-operated 4-way, 2-position cartridge valve, designed as a direct-acting, balanced spool directional valve. This model is engineered to handle up to 5000 psi (350 bar) and does not require a minimum hydraulic pressure for operation, making it versatile for various applications. The valve features a fatigue-rated solenoid tube assembly and offers multiple manual override options, although certain overrides are incompatible with weatherized coils. It incorporates EPDM seals suitable for systems using phosphate ester fluids but not recommended for petroleum-based fluids, which can damage the seals. The DNDAMZN648 employs a wet armature design that immerses the armature in the working fluid, which can be affected by heat generated during prolonged coil energization. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade at high temperatures. The solenoid's magnetic configuration ensures high efficiency with substantial spool actuating force per watt expended, enhancing reliable valve operation. This model supports various coil termination and voltage configurations, some equipped with surge protection. Coils are interchangeable within the Sun Series 1 solenoid range and can be mounted bidirectionally on the tube. Connector options are available with ratings up to IP69K for enhanced environmental protection. The valve's construction minimizes internal component binding due to excessive installation torque or machining variations in cavity/cartridge designs. It fits into a T31A cavity and has a capacity of 10 gpm (40 L/min). The typical response time is 50 ms, with maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports switching frequencies up to 15,000 cycles per hour. The manual override requires a force of approximately 5 lbs/1000 psi at Port 1 and features a stroke length of .10 inches (2.5 mm).

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.
