The Sun Hydraulics DNDYTXV724 (DNDYTXV724) is a solenoid-operated 6-way, 2-position cartridge valve designed for efficient circuit selection. This direct-acting, balanced spool valve allows users to switch between two distinct hydraulic circuits. In its de-energized state, it connects ports P and T to the first circuit; when energized, it reroutes them to the second circuit. The valve is engineered with a fatigue-rated solenoid tube assembly suitable for service pressures up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. Notably, this valve does not require a minimum hydraulic pressure for operation. The DNDYTXV724 offers several manual override options, although these are incompatible with weatherized coils. It features a wet armature design that enhances efficiency by allowing the working fluid to cool the coil-generated heat. However, caution is advised when using water-glycol mixtures as they may degrade over time due to high temperatures. The valve supports various coil termination and voltage configurations with options for surge protection. This model boasts an impressive switching frequency of up to 15,000 cycles per hour and a typical response time of 50 ms. It incorporates Sun's floating style construction, minimizing potential internal binding issues during installation due to torque or machining variations. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. With a capacity of 5 gpm (20 L/min) and maximum leakage at 5 in\u00b3/min (80 cc/min) at 3000 psi (210 bar), this cartridge is well-suited for precise control applications. Its compact build includes specifications like a .75-inch solenoid tube diameter and requires an installation torque of 30-35 lbf ft (41-47 Nm). For maintenance, Viton seal kits are available 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.
