While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics DMDAZRV211 (DMDAZRV211) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. 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 integrated position switch confirms the valve's placement in the spring-biased position, enhancing operational reliability. This cartridge valve is designed as a sealed unit that is factory set and not serviceable in the field. Any required modifications or servicing must be conducted at the factory to avoid voiding the warranty. The design includes a CE-approved position switch and requires specific tools like a crow's foot wrench for installation due to the position switch obstructing deep socket wrench use. The solenoid tube assembly of the DMDAZRV211 is fatigue rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. It operates without minimum hydraulic pressure, allowing for versatile application across various hydraulic systems. Special attention is needed regarding seal compatibility; cartridges with EPDM seals are suited for systems using phosphate ester fluids and must avoid contact with petroleum-based substances. Additionally, this model features a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization. A variety of coil termination and voltage options are available to suit different operational needs and environments. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at specified conditions. The DMDAZRV211 also supports up to 15,000 switching cycles per hour and incorporates Sun\u2019s floating style construction to prevent internal binding due to installation or machining variations.

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.
