The Sun Hydraulics DMDAZRV912 (DMDAZRV912) is a solenoid-operated 3-way, 2-position cartridge valve designed for reliable and efficient operation in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is particularly beneficial in pilot control circuits. The incorporation of a position switch offers confirmation that the valve remains in its spring-biased position. The design includes a wet armature setup where the working fluid surrounds the armature, which could be relevant when considering fluid types and prolonged energization of the coil. It\u2019s important to note that cartridges configured with EPDM seals should only be used with phosphate ester fluids as exposure to petroleum-based fluids can damage these seals. The solenoid tube assembly of this model is fatigue rated for 5000 psi (350 bar) service, ensuring durability and robustness under high-pressure conditions. This model showcases Sun Hydraulics' floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar), and a flow capacity up to 12 gpm (45 L/min), the DMDAZRV912 responds typically within 50 ms and supports up to 15,000 switching cycles per hour. It also offers a variety of coil termination and voltage options, enhancing its adaptability to different system requirements. The valve\u2019s unique magnetic design results in high efficiency, providing strong spool actuating force per Watt expended which facilitates reliable shifting. Installation requires specific tools like a crow's foot wrench due to the position switch setup, with recommended torque settings between 30 \u2013 35 lbf ft (41 \u2013 47 Nm). This model is not field serviceable; any required adjustments or servicing must be handled by returning it to the factory to maintain warranty coverage.

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.
