The Sun Hydraulics DMDAZRV212 (DMDAZRV212) 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 a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. The inclusion of a position switch confirms the valve's status in the spring-biased position, enhancing operational safety and reliability. This non-serviceable, factory-sealed unit must be ordered with a coil and requires specific tools like a crow's foot wrench for installation due to the design of the position switch that obstructs deep socket wrench use. It boasts a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability and reliability even under high-pressure conditions. The valve operates without needing a minimum hydraulic pressure, making it versatile across various applications. Further enhancing its utility are cartridges configured with EPDM seals suitable for systems using phosphate ester fluids; however, these should not be exposed to petroleum-based fluids as it damages the seals. The wet armature design means that the working fluid surrounds the armature which could lead to heat-related degradation of certain fluids over extended periods. The DMDAZRV212 also features diverse coil termination and voltage options, including models with surge protection. Its unique magnetic design contributes to high efficiency and effective spool actuating force per Watt expended, ensuring reliable valve shifting. Sun Hydraulics' floating style construction minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time around 50 ms. The model weighs approximately 0.50 lb (0.25 kg) and offers maximum valve leakage at 110 SUS 24 cSt of about 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar).

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.
