The Sun Hydraulics RPKDBJV (RPKDBJV) is an air-controlled, pilot-operated, balanced piston relief cartridge designed to regulate pressure using compressed air over a diaphragm instead of an adjustable spring. This valve is normally closed and begins to open to the tank port when the inlet pressure reaches the set point, effectively throttling flow to maintain desired pressure levels. Known for its accuracy and smooth operation, this valve is particularly suitable for cross-port relief circuits and can handle maximum pressures at port 2. With a maximum air pressure limit of 150 psi (10 bar), it offers a robust solution with low pressure rise versus flow characteristics. The valve employs Sun's floating style construction to reduce risk of internal binding due to installation torque or machining variations. This Series 4 valve has a capacity of 200 gpm (760 L/min) and operates at a maximum pressure of 2000 psi (140 bar). It features a quick response time of approximately 10 ms and minimal leakage under specified conditions. The RPKDBJV is interchangeable with other two-port relief cartridges within its frame size, sharing the same flow path and cavity dimensions. It fits into a T-18A cavity and requires an installation torque between 350 - 375 lbf ft (474 - 508 Nm). Weighing in at approximately 2.50 lbs (1.15 kg), this valve also supports Viton seal kits for enhanced durability in various applications.
