The Sun Hydraulics DLDAZHN812 (DLDAZHN812) is a high-performance, solenoid-operated 2-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is engineered for precise control in hydraulic systems. It can be configured as either normally open or normally closed based on application requirements. The inclusion of a position switch facilitates confirmation that the valve is in its spring-biased position, enhancing operational reliability and system safety. This model features a robust design with a fatigue rating for the solenoid tube assembly at 5000 psi (350 bar), making it suitable for demanding applications. It has no minimum hydraulic pressure requirement for operation, thanks to its direct actuation. The wet armature design ensures that the working fluid surrounds the armature, which is beneficial for heat dissipation but requires consideration of fluid type to avoid breakdown and varnish formation. Installation considerations include the use of a crow's foot wrench due to the position switch obstructing deep socket wrench use. Various coil termination and voltage options are available to accommodate different system requirements, including options with surge protection. The DLDAZHN812 supports up to 12 gpm (45 L/min) flow capacity and operates with a maximum pressure of 5000 psi (350 bar). Its quick response time (typically 50 ms) and high switching frequency capability (up to 15,000 cycles per hour) make it suitable for systems requiring fast and frequent operations. The cartridge's compact dimensions include a solenoid tube diameter of .75 inches (19 mm) and it weighs approximately .50 lb (0.25 kg). For maintenance or changes in configuration, this sealed unit must be returned to the factory as it is not field serviceable; unauthorized tampering will void its warranty.

This solenoid-operated 2-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The valve is available in either a normally open or normally closed configuration.
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.
- 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.
