The Sun Hydraulics RPEEKBV (RPEEKBV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients by limiting pressure rise. This normally closed, pressure-limiting valve opens to the tank port when the inlet port pressure reaches the valve setting, throttling flow effectively. It features a low-pressure rise versus flow and provides rapid response times, typically around 2 milliseconds. The valve is capable of handling maximum pressures up to 5000 psi (350 bar) and has a capacity of 25 gpm (95 L/min). Notably, it incorporates Sun's floating style construction to minimize potential internal binding due to installation torque or machining variations. The RPEEKBV is suitable for use in cross port relief circuits but should not be used in load holding applications due to spool leakage considerations. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability in various applications. Additionally, back pressure on the tank port is directly additive to the valve setting at a 1:1 ratio. For installation and adjustment, the valve requires specific torque settings: 30 - 35 lbf ft (41 - 47 Nm) for installation and 80 - 90 lbf in. (9 - 10 Nm) for the locknut. The adjustment screw features an internal hex size of 5/32 in. (4 mm), allowing for precision tuning across its full range or up to a specified special setting if required. Overall, this cartridge offers robust performance with interchangeable functionality across similar frame sizes within its series, making it versatile for various hydraulic systems requiring rapid pressure relief capabilities.
