While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics DMDAZBN612 (DMDAZBN612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool with closed transition. This design significantly minimizes oil loss when shifting positions, which is crucial in pilot control circuits. The valve includes a position switch to confirm it remains in the spring-biased position, enhancing operational reliability. Notably, the DMDAZBN612 requires no minimum hydraulic pressure for operation and is designed with a wet armature setup where the working fluid surrounds the armature. This setup can influence fluid integrity under prolonged coil energization, making it suitable for specific applications where these conditions are managed. This valve is built to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features rapid response times typical at 50 ms and maintains low leakage rates. The robust construction includes Sun's floating style design to prevent internal parts binding due to installation torque or cavity/cartridge machining variations. Moreover, it offers various coil termination and voltage options, with choices for surge protection included. The solenoid's unique magnetic layout ensures high efficiency and effective spool actuating force per Watt expended for reliable valve shifting. For installation, specific tools such as a crow's foot wrench are necessary due to the position switch configuration. The DMDAZBN612 is supplied as a sealed unit not serviceable in the field; any required adjustments or servicing must be handled by returning it to the factory. This cartridge also incorporates EPDM seals designed specifically for use with phosphate ester fluids; exposure to other substances like petroleum-based fluids will damage these seals. This model\u2019s adherence to CE standards for its position switch further underscores its compliance with rigorous safety and operational benchmarks.

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.
