The Sun Hydraulics DMDAZBV224 (DMDAZBV224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a crucial aspect for pilot control circuits. The built-in position switch confirms the valve's status, ensuring it remains in the spring-biased position unless actuated. This unit requires the separate purchase of a coil and is delivered as a sealed, factory-set cartridge that is not serviceable in the field. Any required modifications or servicing must be handled by returning the unit to the manufacturer to maintain warranty coverage. The installation of this valve requires specific tools like a crow's foot wrench due to the position switch that obstructs deep socket wrench use. The DMDAZBV224 operates without minimum hydraulic pressure and features EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. It employs a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization. The valve\u2019s solenoid design enhances magnetic efficiency, ensuring reliable spool actuation and minimal energy wastage. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typical at 50 ms. It supports various coil termination and voltage options with optional surge protection and boasts Sun\u2019s floating style construction which reduces internal part binding risks due to installation torque or cavity/cartridge machining discrepancies.

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.
