The Sun Hydraulics DMDAZRN824 (DMDAZRN824) 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, minimizing oil loss during shifting which is crucial in pilot control circuits. The integrated position switch confirms the valve's return to the spring-biased position, enhancing operational reliability. Constructed with a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service and a wet armature design, this model ensures durability and sustained performance even under high thermal conditions within the fluid. The valve operates without minimum hydraulic pressure, making it versatile for various applications. It also incorporates Sun's floating style construction to reduce internal parts binding due to installation torque or cavity/cartridge machining variations. The DMDAZRN824 supports a wide array of coil termination and voltage options, including models with surge protection, providing flexibility for different system requirements. Its unique magnetic design yields high efficiency and reliable spool actuating force per Watt expended. This model has specific configurations where cartridges fitted with EPDM seals are designated for systems using phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 3000 psi not exceeding 5 in\u00b3/min. Installation requires specific tools due to the position switch configuration and has an installation torque between 30 - 35 lbf\u00b7ft (41 - 47 Nm). This model weighs approximately 0.50 lb (0.25 kg), ensuring it is both robust and manageable for integration into various systems.

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.
