The Sun Hydraulics DNDYMXN548 (DNDYMXN548) is a solenoid-operated, 6-way, 2-position cartridge valve designed for versatile hydraulic applications. This direct-acting, balanced spool valve is primarily used to select between two separate circuits. In its de-energized state, it connects P and T to the first circuit, and when energized, it switches to connect P and T to the second circuit. The valve operates efficiently under a maximum pressure of 5000 psi (350 bar) and does not require a minimum hydraulic pressure for operation. It features a fatigue-rated solenoid tube assembly for robust performance. The DNDYMXN548 model offers several manual override options, although these are not compatible with weatherized coils. The manual control assembly has an estimated mechanical life of approximately 7,000 cycles. Its wet armature design ensures that the working fluid surrounds the armature, which can be essential in managing heat generated by the coil during prolonged energization. It is important to note that certain fluids like water-glycol mixtures may degrade over time due to this heat exposure. This cartridge valve incorporates Sun's floating style construction to minimize potential internal binding from excessive installation torque or machining variations in cavity/cartridge configurations. With a capacity of 5 gpm (20 L/min) and typical response time of 50 ms, it supports high-frequency switching up to 15,000 cycles per hour. The valve\u2019s solenoid design yields high actuating force per watt, ensuring reliable shifting capabilities. The product allows for diverse coil termination and voltage configurations with options for surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, coil connector options are available with ratings up to IP69K for enhanced environmental protection.

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.
