The Sun Hydraulics DNCADBV636 (DNCADBV636) is a high-performance, solenoid-operated 4-way, 2-position cartridge valve. It features a direct-acting, balanced spool directional design with a closed transition between positions, which minimizes oil loss during shifting\u2014a crucial factor in pilot control circuits. The valve is engineered to handle a capacity of 8 gpm/30 L/min with port 3 as the inlet and port 1 as the tank, although it allows for reverse flow under specific conditions. This model is robustly constructed to be fatigue rated for up to 5000 psi (350 bar) service and does not require a minimum hydraulic pressure for operation, making it versatile for various applications. The DNCADBV636 comes with EPDM seals suitable for systems using phosphate ester fluids; however, these are susceptible to damage from exposure to petroleum-based fluids. Additionally, the DNCADBV636 uses a wet armature design where the working fluid surrounds the armature that can be exposed to heat generated by the coil if energized for extended periods. This design consideration is vital when using certain fluids such as water-glycol mixtures that may degrade under high temperatures. Sun Hydraulics has equipped this valve with various coil termination and voltage options, including configurations with surge protection. The coils are interchangeable with other Sun Series 1 solenoid products and feature high efficiency due to their unique magnetic design which ensures reliable valve shifting even under demanding conditions. For installation ease and reliability, this model incorporates Sun\u2019s floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With its rapid response time of typically 50 ms and capability of handling up to 15000 switching cycles per hour, the DNCADBV636 is an excellent choice for dynamic systems requiring precise control and durability.
