The Sun Hydraulics RVIACDV (RVIACDV) is a ventable, pilot-operated, balanced piston relief cartridge designed as a normally closed pressure regulating valve. It features an inlet port that opens to the tank port when the pressure reaches the set level, thereby throttling flow to maintain pressure regulation. A distinctive feature is its vent port, which allows for remote control via other pilot or two-way valves, enhancing its versatility in various applications. This valve is known for its accuracy, low-pressure rise versus flow characteristics, smooth and quiet operation, and moderate speed. It can accept maximum pressure at port 2, making it suitable for cross-port relief circuits; however, users should consider spool leakage in such configurations. The RVIACDV model incorporates a main stage orifice protected by a 150-micron stainless steel screen and features Sun's floating style construction to minimize binding risks due to installation torque or machining variations. It requires that the relief valve setting always be higher than the pilot valve setting and is not recommended for load-holding applications due to potential spool leakage. The cartridge with EPDM seals is compatible with phosphate ester fluids but should not be exposed to petroleum-based fluids as this could damage the seals. This model has a cavity of T-19A with a series 4 capacity of 120 gpm (480 L/min) and operates at a maximum pressure of 5000 psi (350 bar). Typical response time is around 10 ms with control pilot flow between 15 - 20 in\u00b3/min (0.25 - 0.33 L/min). The valve requires specific installation torque and adjustments for optimal performance and weighs approximately 3.10 lb (1.40 kg).
