The Sun Hydraulics DMDAZBN824 (DMDAZBN824) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014critical for maintaining efficiency in pilot control circuits. The inclusion of a position switch provides verification that the valve has returned to its spring-biased position, enhancing operational safety and reliability. This model is engineered to be maintenance-free as it comes as a sealed, factory-set unit that is not serviceable in the field. Any required adjustments or servicing must be handled by returning the unit to the factory, ensuring compliance with warranty conditions. It's important to note that this cartridge requires an accompanying coil, which must be ordered separately. The valve's robust design includes a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for high-pressure applications. Its operation does not depend on minimum hydraulic pressure, allowing for versatile usage across various hydraulic setups. The DMDAZBN824 also features EPDM seals configured specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. For installation, specialized tools such as a crow's foot wrench are necessary due to the position switch design which obstructs the use of a deep socket wrench. The valve also boasts a high-efficiency solenoid design that provides strong actuating force per watt expended and incorporates Sun\u2019s floating style construction to prevent internal binding caused by excessive installation torque or cavity/cartridge machining variations. Overall, the Sun Hydraulics DMDAZBN824 offers reliable performance and efficient operation suited for various applications requiring precise fluid control with minimal leakage and high switching frequency capabilities.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
The position switch provides confirmation that the valve is in the spring biased position.
- A coil must be ordered with this cartridge. This cartridge is supplied as a sealed, factory set unit and is not field serviceable. If the assembly requires changes or service it needs to be returned to the factory. Any tampering will violate the product warranty.
- Position switch is CE approved.
- When torquing this cartridge into its cavity, a crow's foot wrench or similar will be required since the position switch precludes the use of a deep socket wrench.
- 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.
- Cartridges configured 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.
- 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.
