The Sun Hydraulics DMDAZBV912 (DMDAZBV912) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features closed transition between positions, which significantly minimizes oil loss during shifting\u2014crucial for maintaining efficiency in pilot control circuits. The valve includes a position switch that confirms when it is in the spring-biased position, enhancing operational reliability and safety. Constructed to be robust and durable, the DMDAZBV912 has a solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar), making it suitable for high-pressure applications. It operates without requiring a minimum hydraulic pressure, thus offering versatility across various hydraulic systems. The cartridge's design incorporates Sun Hydraulics' floating style construction which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. This model also features a wet armature design where the working fluid surrounds the armature and absorbs heat from the coil. This configuration can affect fluid properties over extended periods of energization; therefore, it is important to consider fluid type in application decisions. Cartridges with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids will compromise seal integrity. The DMDAZBV912 supports various coil termination and voltage options, including configurations with surge protection, allowing customization to meet specific application requirements. Its efficient magnetic design ensures high spool actuating force per watt expended, leading to reliable valve shifting even under demanding conditions. The model's quick response time and capacity for high switching frequencies make it an excellent choice for systems requiring rapid dynamic responses.

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.
