The Sun Hydraulics RVCBCCN (RVCBCCN) is a versatile three-port, normally closed modulating element with relief, designed to perform dual functions when paired with an external orifice. This component acts as a bypass compensator, regulating a priority flow into the circuit while redirecting excess input flow to the tank port 2. In scenarios where the inlet port 1 pressure exceeds the valve setting, it functions as a conventional relief valve. The compensating pressure varies across ranges: 45 psi (3 bar) for A range, 30 psi (2 bar) for B range, and 100 psi (7 bar) for C range. The valve's performance is depicted through a curve chart where system pressure is plotted against the pressure differential created across the control orifice. Notably, this valve's capacity and performance are contingent upon bypass flow rather than control flow. The RVCBCCN model features a T-11A cavity and Series 1 capacity of up to 10 gpm (40 L/min), with factory pressure settings established at 4 gpm (15 L/min). It operates under a maximum pressure of 5000 psi (350 bar) and exhibits typical response times of around 10 milliseconds. Valve leakage at 110 SUS (24 cSt) is limited to approximately 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Adjustments are made via clockwise turns to increase settings up to five full turns, with specific torque requirements for installation and locknut adjustments. The unit weighs approximately .40 lb (.20 kg), and it utilizes Viton seals for effective operation.
