The Sun Hydraulics DMDAZRV612 (DMDAZRV612) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve ensures minimal oil loss during position transitions due to its closed transition design, which is particularly beneficial in pilot control circuits. The valve features a position switch that confirms the spring-biased position, enhancing operational reliability and safety. Constructed with durability and efficiency in mind, the DMDAZRV612 includes a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for rigorous service conditions. Its direct actuation mechanism requires no minimum hydraulic pressure, allowing for versatile application in various hydraulic systems. The valve is engineered with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The wet armature design of the DMDAZRV612 means that the working fluid surrounds the armature. While this aids in cooling, prolonged energization can lead to fluid degradation at high temperatures. This valve also features multiple coil termination and voltage options, providing adaptability for different electrical requirements and environments. Installation considerations include the use of a crow\u2019s foot wrench due to the position switch configuration that prevents deep socket wrench usage. The product's robust magnetic design delivers high efficiency and reliable valve shifting performance by maximizing spool actuating force per watt expended. This model incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, the DMDAZRV612 offers both performance and reliability for advanced hydraulic systems.

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.
