The Sun Hydraulics RVBALCV (RVBALCV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve is typically used to maintain a specific pressure level by opening to tank port 2 when the inlet pressure at port 1 exceeds the set threshold. The RVBALCV features a vent port (port 3) that enables remote control via other pilot or two-way valves, offering versatility in various control applications. Notably, this valve can handle maximum pressures at port 2 and is suitable for cross-port relief circuits, although spool leakage should be considered in such configurations. It has a minimum setting of 75 psi (5 bar) across all spring ranges but is not recommended for load-holding applications due to potential spool leakage. The design incorporates Sun's floating style construction to reduce the risk of internal component binding from excessive installation torque or machining variations. The main stage orifice is safeguarded against contamination, ensuring reliable performance under demanding conditions. The RVBALCV operates with a capacity of 7.5 gpm (30 L/min), and its factory pressure settings are established at a flow rate of 4 gpm (15 L/min). With a maximum operating pressure of 5000 psi (350 bar) and typical response time of around 10 ms, this valve offers swift and smooth operation with low pressure rise relative to flow. Additionally, the valve features an adjustment mechanism allowing up to five clockwise turns to increase the setting, with specific torque requirements for installation and adjustment components. It has a maximum leakage rate of 2 in\u00b3/min at 110 SUS (24 cSt) viscosity under pressure conditions up to 1000 psi (70 bar). This robust design ensures that it meets various hydraulic system needs while maintaining stability and ease of adjustment.
