The Sun Hydraulics DNDYXXN724 (DNDYXXN724) is a solenoid-operated 6-way, 2-position cartridge valve designed for efficient hydraulic circuit selection. This direct-acting, balanced spool valve is typically utilized to alternate between two separate circuits by connecting P and T to the first circuit when de-energized and switching to the second circuit when energized. It is engineered with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability in high-pressure applications. The valve operates without requiring minimum hydraulic pressure, offering flexibility in various operational settings. The DNDYXXN724 model features multiple manual override options, including configurations without manual override, although these functionalities are not compatible with weatherized coils. The valve employs a wet armature design, which allows the working fluid to cool the coil but may lead to varnish formation over time with certain fluids like water-glycol mixtures if continuously energized. A wide range of coil termination and voltage options are available, providing adaptability for different electrical setups, and it boasts high efficiency due to its unique magnetic design that enhances spool actuating force per watt. This cartridge incorporates Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. It fits into a T-61A cavity and belongs to Series 1 with a capacity of 5 gpm (20 L/min). The typical response time is around 50 ms, with maximum leakage at specified conditions being 5 in\u00b3/min (80 cc/min). Its robust design supports a switching frequency of up to 15,000 cycles per hour. For maintenance and compatibility purposes, Viton seal kits are available for both the 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.
