The Sun Hydraulics DNCALCV836 (DNCALCV836) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve. It features a direct-acting, balanced spool directional valve design with a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial feature in pilot control circuits. The valve's operation does not require a minimum hydraulic pressure, making it highly effective and versatile for various applications. With a capacity of 8 gpm/30 L/min based on port 3 as the inlet and port 1 as the tank, the DNCALCV836 offers robust performance parameters including a maximum operating pressure of 5000 psi/350 bar. It also boasts quick response times, typically around 50 ms. However, it is advised that reverse flow should be avoided as optimal performance cannot be guaranteed under such conditions. The DNCALCV836 utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The wet armature design of the valve ensures that the working fluid surrounds the armature which can be subjected to heat if the coil is energized for extended periods. This could affect fluid integrity over time. Additionally, this model incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The solenoid's unique magnetic design enhances efficiency by providing high spool actuating force per Watt expended, ensuring reliable valve shifting. This model is compatible with other Sun Series 1 solenoid products regarding coil interchangeability and can accommodate various coil termination and voltage options\u2014some even with surge protection. For environments requiring more robust protection against elements, additional weatherized coils and kits are available to further safeguard the system\u2019s operation.
