The Sun Hydraulics RPEEJBV (RPEEJBV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This normally closed, pressure-limiting valve opens rapidly when the inlet port pressure reaches the valve setting, directing flow to the tank port to manage pressure rise effectively. It features a low-pressure rise versus flow and operates with exceptional speed. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability in operation. While it can handle maximum pressure at port 2 and is suitable for cross-port relief circuits, users should consider spool leakage when used in such applications. It is not recommended for load-holding applications due to this leakage characteristic. The RPEEJBV incorporates Sun's floating style construction, which minimizes internal part binding caused by excessive installation torque or machining variations in the cavity/cartridge. The valve's capacity is rated at 25 gpm (95 L/min) with maximum operating pressures of up to 5000 psi (350 bar). With a typical response time of 2 ms and minimal leakage rates at specified conditions, this cartridge ensures efficient and reliable performance. Adjustment options are available through the W or Y controls, allowing for full range adjustability unless a special setting is specified. Installation requires specific torque settings: valve installation torque ranges from 30-35 lbf ft (41-47 Nm), while locknut torque should be between 80-90 lbf in (9-10 Nm). The design also supports interchangeable use among all two-port relief cartridges within its frame size, providing flexibility and ease of maintenance across various applications.
