The Sun Hydraulics RPKDBBV (RPKDBBV) is an air-controlled, pilot-operated, balanced piston relief cartridge designed to use compressed air over a diaphragm to control pressure settings. This valve is typically applied in scenarios requiring precise pressure regulation and is particularly suitable for use in cross-port relief circuits. The RPKDBBV features a normally closed pressure regulating mechanism, which opens to the tank port once the inlet pressure reaches the set threshold, thus throttling flow to maintain the desired pressure level. With its accurate performance and low-pressure rise versus flow characteristics, this valve operates smoothly and quietly with moderate speed. This cartridge can handle a maximum operating pressure of up to 2000 psi (140 bar) and accepts maximum air pressures not exceeding 150 psi (10.5 bar). It incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. The RPKDBBV is interchangeable with other 2-port relief cartridges of the same frame size, offering versatility in application. The valve's capacity is rated at 200 gpm (760 L/min), with a typical response time of 10 ms. It has a maximum valve leakage of 5 in\u00b3/min at 110 SUS (80 cc/min at 70 bar). The hex size measures 1-5/8 inches (41.3 mm), and installation torque ranges from 350 to 375 lbf-ft (474 to 508 Nm). Weighing approximately 2.50 lb (1.15 kg), it uses Viton seals for durability under various conditions. Overall, the Sun Hydraulics RPKDBBV offers reliable performance for applications demanding precise pressure control, ensuring safety and efficiency in hydraulic systems where it is deployed.
