The Sun Hydraulics DLDAZHN812N (DLDAZHN812N) is a high-performance, solenoid-operated 2-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve can be configured as either normally open or normally closed, depending on the requirements of the system it is integrated into. It features a position switch that confirms the valve's status in its spring-biased position, enhancing operational reliability and safety. This robust model has a maximum operating pressure capacity of 5000 psi (350 bar) and a flow capacity up to 12 gpm (45 L/min), making it suitable for a wide range of medium to high-pressure applications. The DLDAZHN812N is designed with a wet armature setup, where the working fluid surrounds the armature. This design consideration is crucial for applications where the valve might be energized for extended periods since some hydraulic fluids can degrade under prolonged exposure to heat. Additionally, it boasts a quick response time of typically 50 ms and supports switching frequencies up to 15,000 cycles per hour, ensuring efficient performance in systems requiring frequent cycling. Installation requires specific tools due to the presence of the position switch; standard deep socket wrenches cannot be used, and a crow\u2019s foot wrench or similar tool is recommended. The cartridge's solenoid tube assembly is fatigue rated for sustained high-pressure operation. It also features Sun Hydraulics' floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This model's durability and reliability are further underscored by its design not being field serviceable; any required adjustments or servicing must be done at the factory to ensure adherence to quality standards and warranty conditions.
