The Sun Hydraulics DMDAZRN924 (DMDAZRN924) is a solenoid-operated, 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This model features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial aspect for pilot control circuits. It includes a position switch that confirms the valve is in the spring-biased position, enhancing operational certainty and safety. The DMDAZRN924 requires an accompanying coil to function, which must be ordered separately. The entire cartridge is supplied as a sealed unit that is factory set and not serviceable in the field; any required modifications or servicing must be done at the factory to avoid voiding the warranty. The valve's solenoid tube assembly is fatigue rated for robust performance up to 5000 psi (350 bar), ensuring reliability under high-pressure conditions. This model is equipped with EPDM seals suitable for use with phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. Its wet armature design allows the working fluid to surround the armature, which could affect fluid integrity if exposed to prolonged heat from an energized coil. Designed with a variety of coil termination and voltage options, the DMDAZRN924 offers flexibility for different system requirements. The solenoid\u2019s unique magnetic design ensures high efficiency and effective spool actuating force per Watt expended. Additionally, Sun\u2019s floating style construction minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and a flow capacity up to 12 gpm (45 L/min). Installation requires specific tools due to its design configuration; using a crow's foot wrench or similar tool is recommended because of the position switch setup. This model has proven suitable for various hydraulic applications where precise control and reliability are essential.

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.
