The Sun Hydraulics DMDAZRN223 (DMDAZRN223) is a high-performance 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 minimizes oil loss during shifting\u2014crucial for maintaining efficiency in pilot control circuits. The integrated position switch confirms the valve's placement in the spring-biased position, enhancing operational reliability. Notably, the DMDAZRN223 is engineered with a fatigue-rated solenoid tube assembly capable of withstanding pressures up to 5000 psi (350 bar), making it suitable for rigorous applications. The cartridge operates without minimum hydraulic pressure, facilitating versatile use across various hydraulic setups. It incorporates Sun\u2019s floating style construction that prevents internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. The valve's wet armature design means the working fluid surrounds the armature; while this aids in efficient operation, prolonged energization can lead to fluid breakdown, especially with water-glycol mixtures. Users should consider fluid compatibility carefully; cartridges configured with EPDM seals are specifically designed for phosphate ester fluids and must avoid contact with petroleum-based substances to prevent seal damage. Installation requires specific tools like a crow's foot wrench due to the position switch obstructing deep socket wrench use. The DMDAZRN223 supports a range of coil termination and voltage options, enhancing its adaptability for different system requirements. Each cartridge is factory-sealed and not serviceable in the field to ensure integrity and performance as per design specifications. Any modifications or required services must be handled directly through factory returns to uphold product warranty conditions.

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.
