The Sun Hydraulics DNDATUN72499 (DNDATUN72499) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered with a fatigue-rated solenoid tube assembly, it supports up to 5000 psi (350 bar) service without requiring a minimum hydraulic pressure for operation. This model offers multiple manual override options, though manual override functionality is incompatible with weatherized coils. The D and L control models feature a detent mechanism intended for temporary actuation with an approximate mechanical life expectancy of 7,000 cycles. The valve is compatible with systems using phosphate ester fluids when equipped with EPDM seals, but exposure to petroleum-based fluids can damage these seals. The wet armature design allows the working fluid to surround the armature and absorb heat from the coil, which may impact function if the coil remains energized for extended periods. A range of coil termination and voltage configurations are available, including those with surge protection, providing flexibility in various applications. The unique magnetic design of the solenoid ensures high efficiency by delivering substantial spool actuating force per watt consumed. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options provide ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce internal part binding due to excessive installation torque or machining variations in cavity/cartridge assembly. With a cavity size of T-31A and series designation of 1, this cartridge has a capacity of 10 gpm (40 L/min), maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), and switching frequency capability up to 15,000 cycles/hr.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- 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.
- 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.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
