The Sun Hydraulics DNDYLXN648 (DNDYLXN648) is a solenoid-operated, 6-way, 2-position cartridge valve designed for efficient circuit selection between two separate hydraulic circuits. In its de-energized state, it connects ports P and T to the first circuit, while energizing the solenoid shifts the connection to the second circuit. This valve features a direct-acting, balanced spool design and operates effectively without requiring a minimum hydraulic pressure. It boasts a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). The valve's manual override options include configurations with or without a detent mechanism, although weatherized coils are not compatible with manual override functionality. Notable for its wet armature design, this valve allows working fluid to surround the armature, which can be influenced by heat generated during coil energization over extended periods. A variety of coil termination and voltage options are available, including those with surge protection. The high-efficiency solenoid design ensures reliable valve shifting by delivering significant spool actuating force per watt expended. The Sun floating style construction minimizes potential binding of internal parts due to installation torque or machining variations. This model fits into cavity T-61A and belongs to Series 1 with a capacity of 5 gpm (20 L/min). It has an impressive switching frequency of up to 15,000 cycles per hour and typical response time of 50 milliseconds. Key specifications include a maximum operating pressure of 5000 psi (350 bar), maximum leakage at specified viscosity of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), and manual override force requirement of approximately 5 lbs at specific port pressures. The valve's installation torque ranges from 30 to 35 lbf\u00b7ft (41 to 47 Nm) and weighs approximately .60 lb (.30 kg).

This solenoid-operated 6-way, 2-position cartridge is a direct-acting, balanced spool valve. The typical use for this valve is to select between two separate circuits. The de-energized condition connects P and T to the first circuit and when energized connects P and T to the second circuit.

  • 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.
  • 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.
  • 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.
  • 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.
