The Sun Hydraulics DMDAZBV824 (DMDAZBV824) is a solenoid-operated, 3-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional control and closed transition between positions. This design feature minimizes oil loss during position shifts, making it particularly beneficial for pilot control circuits. The valve includes a position switch that confirms when it is in the spring-biased position, enhancing operational safety and reliability. This model requires an accompanying coil to function and comes as a factory-sealed unit that is not serviceable in the field. Any required modifications or servicing must be conducted at the factory to avoid voiding the warranty. The valve's installation necessitates specific tools like a crow's foot wrench due to the presence of the position switch which obstructs the use of a deep socket wrench. Rated for up to 5000 psi (350 bar), the solenoid tube assembly of DMDAZBV824 is fatigue rated for high-pressure applications. It operates without needing a minimum hydraulic pressure, offering versatility across various hydraulic systems. Notably, cartridges with EPDM seals are designed exclusively for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The valve features a wet armature design where the working fluid surrounds the armature which might be susceptible to heat during prolonged coil energization. This model supports multiple coil termination and voltage options, providing flexibility in configuring according to specific system requirements. Its magnetic design ensures high efficiency and effective spool actuation force per watt expended, leading to reliable operation even under varying conditions. Additionally, Sun Hydraulics incorporates their floating style construction into this model which helps mitigate potential internal part binding due to installation torque or cavity/cartridge machining discrepancies.

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.
