The Sun Hydraulics DNDYDXN548 (DNDYDXN548) is a solenoid-operated 6-way, 2-position cartridge valve designed for selecting between two separate circuits. In its de-energized state, it connects P and T to the first circuit, and when energized, it connects P and T to the second circuit. This direct-acting valve features a balanced spool design and does not require any minimum hydraulic pressure for operation. It is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve includes various manual override options, though manual override functionality is not compatible with weatherized coils. The DNDYDXN548 utilizes a wet armature design where the working fluid surrounds the armature, which can affect performance if the coil remains energized for extended periods due to heat exposure. It offers a range of coil termination and voltage options with or without surge protection, and the coils are interchangeable with other Sun Series 1 solenoid products. The unique magnetic design of the solenoid enhances efficiency by providing high spool actuating force per watt expended, resulting in reliable valve shifting. This cartridge features Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It fits into a T-61A cavity and has a capacity of 5 gpm (20 L/min). The typical response time is 50 ms, with maximum valve leakage at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). It supports switching frequencies up to 15,000 cycles per hour. Additional specifications include manual override force requirements of 5 lbs/1000 psi at Port 1 and an installation torque of 30 - 35 lbf ft (41 - 47 Nm). Seal kits are available in Viton material for both cartridge and coil components.

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.
