The Sun Hydraulics DNDYLXV636 (DNDYLXV636) is a solenoid-operated, 6-way, 2-position cartridge valve designed for direct-acting and balanced spool applications. This versatile valve is primarily used for selecting between two separate hydraulic circuits. When in the de-energized state, it connects ports P and T to the first circuit, while energizing it connects these ports to the second circuit. The solenoid tube assembly of this valve is fatigue-rated for service pressures up to 5000 psi (350 bar), making it suitable for demanding applications. Notably, this valve operates without requiring any minimum hydraulic pressure. The DNDYLXV636 model offers several manual override options, including a temporary actuation detent mechanism with a mechanical life expectancy of approximately 7,000 cycles in models equipped with D or L controls. However, it's important to note that manual override features are not compatible with weatherized coils. The valve utilizes a wet armature design where the working fluid surrounds the armature; this can impact performance if certain fluids like water-glycol mixtures break down at high temperatures over time. A key advantage of this model is its high-efficiency solenoid design that provides robust spool actuation force per watt expended, ensuring reliable operation. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With coil connector options rated up to IP69K, users have access to enhanced environmental protection through additional weatherized coils and kits. This cartridge incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations. It fits into a T-61A cavity and has a capacity of 5 gpm (20 L/min). With a typical response time of 50 ms and maximum leakage at 5 in\u00b3/min (80 cc/min) at 3000 psi (210 bar), this model ensures efficient switching frequency up to 15,000 cycles per hour.

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.
