The Sun Hydraulics DMDAZBV212 (DMDAZBV212) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for applications requiring reliable control in hydraulic systems. It features a closed transition between positions, which minimizes the loss of oil during shifting\u2014a crucial factor in maintaining the efficiency of pilot control circuits. The valve includes a position switch that confirms its status in the spring-biased position, enhancing operational safety and consistency. Notably, this model is engineered with a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for rigorous industrial applications. The DMDAZBV212 operates without requiring a minimum hydraulic pressure, thus facilitating its use across various low and high-pressure environments. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. Additionally, the wet armature design of the valve ensures that the working fluid surrounds the armature\u2014this is an important consideration as prolonged energization can lead to fluid breakdown at high temperatures. Installation demands specific tools due to its design; a crow's foot wrench is necessary since the position switch obstructs deep socket wrench use. The product comes as a sealed unit from Sun Hydraulics and is not serviceable in the field; any required adjustments or servicing must be handled by returning it to the factory to maintain warranty coverage. With options for various coil terminations and voltages available, including models with surge protection, this versatile valve meets diverse operational needs while maintaining robust performance through Sun\u2019s unique magnetic design and floating style construction. This construction approach notably minimizes internal part binding caused by excessive installation torque or cavity/cartridge machining variations.

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.
