The Sun Hydraulics DMDAZRV924 (DMDAZRV924) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve offers a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial feature in pilot control circuits. The inclusion of a position switch confirms that the valve remains in the spring-biased position, enhancing operational reliability. This valve must be paired with a coil, which is ordered separately to meet specific system requirements. The DMDAZRV924 is delivered as a sealed unit; it is factory set and not serviceable in the field. Any attempt to tamper with or modify the cartridge voids its warranty and necessitates factory return for any service or adjustments. Featuring a fatigue rating of 5000 psi (350 bar), this valve operates without requiring minimum hydraulic pressure, making it highly effective and versatile across various applications. It is equipped with EPDM seals suitable for systems using phosphate ester fluids; these seals must not be exposed to petroleum-based fluids as they can cause damage. The DMDAZRV924 employs a wet armature design where the working fluid surrounds the armature\u2014this could lead to fluid breakdown if the coil remains energized for extended periods. Various coil termination and voltage options are available including options with surge protection. Its unique magnetic design allows for high efficiency and dependable spool actuating force per watt expended. Installation requires specific tools such as a crow's foot wrench due to the design of the position switch which blocks deep socket wrench usage. The solenoid tube assembly\u2019s dimensions and installation torque specifications ensure compatibility with standardized cavities while maintaining ease of installation without risking internal binding due to excessive torque 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.
