The Sun Hydraulics RPEELBV (RPEELBV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to safeguard hydraulic components from pressure transients. This normally closed, pressure-limiting valve is engineered to open rapidly when the inlet port 1 reaches the designated valve setting, diverting flow to tank port 2 to manage pressure increases. It features a low pressure rise versus flow characteristic and operates with exceptional speed. The valve can withstand maximum pressure at port 2, making it suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The main stage orifice is shielded by a 150-micron stainless steel screen, enhancing its durability and performance. This cartridge is not recommended for load-holding applications due to potential spool leakage. Back pressure on tank port 2 directly affects the valve setting at a 1:1 ratio. All two-port relief cartridges except pilot reliefs are interchangeable within their frame size, offering consistent flow paths and cavity compatibility. The RPEELBV incorporates Sun's floating style construction to minimize internal part binding from excessive torque or machining variations. With a capacity of 25 gpm (95 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve provides reliable performance with typical response times of approximately 2 ms. Maximum valve leakage is rated at 2 in\u00b3/min (1000 psi) or 30 cc/min (70 bar). Adjustments can be made using the W or Y control over its full range unless a special setting is specified; adjustment involves up to five clockwise turns. The valve has an installation torque range of 30-35 lbf ft (41-47 Nm), weighs .30 lb (.15 kg), and includes a Viton seal kit option for enhanced sealing capabilities.
