The Sun Hydraulics DMDAZBN212 (DMDAZBN212) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a critical feature for maintaining the integrity and efficiency of pilot control circuits. The inclusion of a position switch provides reliable confirmation that the valve remains in the spring-biased position. This product comes as a sealed, factory-set unit ensuring optimal performance and reliability but is not serviceable in the field; any required adjustments or servicing must be handled by returning it to the factory. It's important to note that any tampering with the cartridge will void its warranty. The valve's design incorporates a CE-approved position switch and requires specific tools like a crow's foot wrench for installation due to the position switch blocking deep socket wrench access. Engineered for durability, the solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service. The DMDAZBN212 operates without needing a minimum hydraulic pressure, adding to its versatility across various applications. Special attention is needed regarding seal selection; cartridges with EPDM seals are intended for systems using phosphate ester fluids and must avoid contact with petroleum-based substances which can degrade the seals. This model also features a wet armature design where operating fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization due to heat exposure. Various coil termination and voltage options are available to suit different system requirements, enhancing adaptability while maintaining high efficiency and reliable valve shifting through its unique magnetic design. The floating style construction minimizes internal binding risks, further ensuring consistent performance even under variable installation conditions or cavity 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.
