The Sun Hydraulics DMDAZRV224 (DMDAZRV224) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. Featuring a direct-acting, balanced spool directional valve design, it ensures minimal oil loss during position transitions due to its closed transition configuration. This attribute is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. The valve includes a position switch that confirms its status in the spring-biased position, enhancing operational safety and reliability. Constructed to be robust under high-pressure conditions, the DMDAZRV224 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity up to 12 gpm (45 L/min). Its quick response time of approximately 50 ms and a switching frequency of up to 15000 cycles per hour make it suitable for applications requiring fast and frequent operations. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and long service life. This model incorporates Sun Hydraulics' unique floating style construction which minimizes internal parts binding \u2014 a common issue caused by excessive installation torque or variations in cavity/cartridge machining. It also features a wet armature design; hence it's crucial to consider the type of fluid used as some fluids may degrade at higher temperatures influenced by prolonged coil energization. For installation, specific tools such as a crow's foot wrench are recommended due to the positioning of the switch which obstructs the use of a deep socket wrench. Users should note that any tampering with this factory-set sealed unit voids its warranty and any required adjustments or servicing must be handled directly through Sun Hydraulics' factory facilities.

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.
