The Sun Hydraulics RVCACAV (RVCACAV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precision pressure regulation. This normally closed valve opens to the tank port when inlet pressure reaches the set threshold, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control via other pilot or two-way valves, ensuring versatility in various applications. The RVCACAV is recognized for its accuracy, low-pressure rise versus flow characteristics, smooth operation, and moderate speed. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should consider spool leakage when using it in such configurations. The main stage orifice of the valve is safeguarded by a 150-micron stainless steel screen, enhancing durability and reliability. While not recommended for load-holding applications due to potential spool leakage, the valve's backpressure on the tank port directly adds to the valve setting at a 1:1 ratio. The cartridge is constructed with Sun's floating style design to minimize internal binding risks due to excessive installation torque or machining variations. The RVCACAV has a cavity size of T-11A and a series capacity of 15 gpm (60 L/min), with factory pressure settings established at 4 gpm (15 L/min). It boasts a maximum operating pressure of 5000 psi (350 bar) and control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Typical response time is around 10 ms, with maximum valve leakage at approximately 2 in\u00b3/min (30 cc/min) under specified conditions. The valve's adjustment requires up to five clockwise turns to increase settings and features specific torque requirements for installation and locknut adjustments.
