The Sun Hydraulics RVIDLEV (RVIDLEV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to tank port 2 when the inlet port 1 pressure reaches the set level, effectively throttling flow to maintain desired pressure levels. It features a vent port 3 for remote control and a drain port 4 that ensures insensitivity to back pressure, enhancing its accuracy and smooth operation. The valve is equipped with a 150-micron stainless steel screen protecting the main stage orifice and is not recommended for load-holding applications due to spool leakage considerations. The RVIDLEV model can handle maximum pressures at port 2 and is suitable for cross-port relief circuits, although spool leakage should be considered in such applications. The valve's construction incorporates Sun's floating style design to prevent internal part binding from excessive torque or machining variations. It can operate at pressures up to 5000 psi (350 bar) and has a capacity of handling flow rates up to 120 gpm (480 L/min). The response time is typically around 10 milliseconds with pilot control flow between 15-20 in\u00b3/min (0.25 - 0.33 L/min). This model requires specific installation parameters including a torque setting of 350-375 lbf-ft (474-508 Nm) and features an adjustment screw internal hex size of 5/32 inch (4 mm). Additionally, it weighs approximately 3.10 lb (1.40 kg) and uses Viton seals suitable for phosphate ester fluids but not compatible with petroleum-based substances.
