The Sun Hydraulics DMDAZRN612 (DMDAZRN612) is a solenoid-operated, 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool valve features a closed transition between positions, minimizing oil loss during shifting\u2014critical for maintaining efficiency in pilot control circuits. It includes a position switch that confirms when the valve is in its spring-biased position, enhancing operational safety and reliability. This model comes as a sealed unit and is not serviceable in the field; any required adjustments or repairs must be handled by returning it to the manufacturer. The DMDAZRN612 utilizes EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. Its wet armature design allows the working fluid to surround the armature, which could lead to thermal degradation of certain fluids over extended periods of energization. The valve operates without needing a minimum hydraulic pressure and boasts a fatigue rating for up to 5000 psi (350 bar). It supports a variety of coil termination and voltage options and incorporates Sun's unique magnetic design for high efficiency, ensuring robust performance with high spool actuating force per Watt expended. The construction features Sun's floating style to prevent internal binding due to installation torque or machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), operating pressures up to 5000 psi (350 bar), typical response times around 50 ms, and maximum leakage at 110 SUS (24 cSt) being 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The solenoid tube diameter measures .75 inches (19 mm), and installation requires specific tools due to the position switch configuration. This model weighs approximately .50 lb (0.25 kg).

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.
