The Sun Hydraulics RVCAODV (RVCAODV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. These cartridges are normally closed pressure regulating valves that open to the tank port when the inlet port pressure reaches the valve setting, thereby regulating flow to maintain desired pressure levels. They feature a vent port that allows for remote control via other pilot or 2-way valves. The RVCAODV model is known for its accuracy, low-pressure rise versus flow characteristics, smooth and quiet operation, and moderate response speed. One key feature of this cartridge is its ability to accept maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice is protected by a 150-micron stainless steel screen to enhance durability and performance. It is important to note that these cartridges are not suitable for load-holding applications due to potential spool leakage. The RVCAODV model incorporates Sun's floating style construction, which helps minimize internal part binding due to excessive installation torque or cavity/cartridge machining variations. This product can handle a maximum operating pressure of 5000 psi (350 bar) with a control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a typical response time of 10 ms. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are available; however, exposure to petroleum-based fluids can damage these seals. Installation requires specific torque settings and adjustments using hex tools as specified in the product documentation. With a capacity of up to 15 gpm (60 L/min), this cartridge valve offers reliable performance for various hydraulic applications where precise pressure control is crucial.
