The Sun Hydraulics DNDAMYV648 (DNDAMYV648) is a solenoid-operated 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional design. This valve is engineered for a fatigue rating of up to 5000 psi (350 bar), ensuring robust performance in demanding hydraulic systems. It operates without the need for a minimum hydraulic pressure, making it versatile for various applications. The valve offers several manual override options, although these are not compatible with weatherized coils. Notably, the D and L control models feature a detent mechanism intended for temporary actuation with an estimated mechanical life of approximately 7,000 cycles. The valve's wet armature design allows the working fluid to cool the armature and coil, which is crucial if the coil remains energized over extended periods. However, care should be taken with fluids like water-glycol mixtures that may degrade at elevated temperatures. The DNDAMYV648 offers various coil termination and voltage configurations, including surge protection options. Its high-efficiency solenoid design provides significant spool actuating force per watt consumed, ensuring reliable valve operation. Additionally, this model features interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve also supports coil connectors rated up to IP69K for enhanced environmental protection. Employing Sun's floating style construction reduces the risk of internal component binding from excessive installation torque or machining variances in cavity/cartridge interfaces. The DNDAMYV648 fits into a T-31A cavity and belongs to Series 1 with a capacity of up to 10 gpm (40 L/min). It has a typical response time of 50 ms and can handle switching frequencies up to 15,000 cycles per hour. This model weighs approximately .60 lb (.30 kg) and requires specific Viton seal kits for both cartridge and coil maintenance.

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.
