***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. 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 DMDAZRV624 (DMDAZRV624) is a solenoid-operated, 3-way, 2-position cartridge valve that features a direct-acting, balanced spool with a closed transition between positions. This design significantly reduces the loss of oil during shifting, making it particularly beneficial for pilot control circuits. The valve includes a position switch to confirm it remains in the spring-biased position. Notably, this cartridge must be combined with a separately ordered coil and is delivered as a sealed unit that is not field serviceable; any required modifications or servicing must be handled directly by the factory. The DMDAZRV624 valve is designed with a wet armature setup where the working fluid surrounds the armature. This configuration can affect fluid integrity if the coil remains energized for extended periods, especially with water-glycol mixtures which may degrade and form varnish affecting cartridge functionality. Its solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring robust performance in demanding applications. The model also features EPDM seals suitable for systems using phosphate ester fluids, although these seals are vulnerable to damage from exposure to petroleum-based substances. Additional technical specifications of the DMDAZRV624 include a maximum flow capacity of 12 gpm (45 L/min), and a typical response time of 50 ms. It supports up to 15000 switching cycles per hour and can handle maximum operating pressures of up to 5000 psi (350 bar). Its design incorporates Sun\u2019s floating style construction which minimizes internal part binding due to installation torque or machining variations in cavity-cartridge setups. Various coil termination and voltage options are available for this model, enhancing its adaptability for different system requirements.

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.
