The Sun Hydraulics DMDAZRV223 (Material Number DMDAZRV223) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control in various applications. This direct-acting, balanced spool directional valve ensures a closed transition between positions, significantly minimizing oil loss during shifting which is crucial in maintaining the efficiency of pilot control circuits. The inclusion of a position switch provides reliable confirmation that the valve is in the spring-biased position, enhancing operational safety and accuracy. This model requires a separately ordered coil and comes as a sealed unit not intended for field servicing; any required modifications or servicing must be conducted at the factory to maintain warranty coverage. The design incorporates CE-approved position switches and utilizes a wet armature setup where the working fluid surrounds the armature. This configuration necessitates consideration of fluid type as EPDM seals used are only compatible with phosphate ester fluids and adverse reactions occur with petroleum-based substances. The DMDAZRV223 supports up to 12 gpm/45 L/min flow capacity and can handle maximum operating pressures of 5000 psi/350 bar. Its rapid response time (typically 50 ms) and maximum valve leakage at 110 SUS (24 cSt) of 5 in\u00b3/min at 3000 psi make it highly efficient for fast-paced operations. The solenoid's unique magnetic design enhances efficiency by maximizing spool actuating force per watt expended, ensuring reliable valve shifting even under high switching frequencies (up to 15000 cycles/hr). Installation requires specific tools due to its design, with recommended torque settings provided for optimal performance. This model also features Sun's floating style construction to prevent internal parts binding from installation stresses or machining variations, further ensuring reliability and longevity of the valve system in demanding environments.

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.
