The Sun Hydraulics RVCBLDN (RVCBLDN) is a versatile hydraulic component designed as a three-port normally closed modulating element with relief. This product serves dual functions when used alongside an external orifice. Primarily, it acts as a bypass compensator that manages priority flow into the circuit, which is determined by the external orifice. Any input flow that exceeds this priority flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 increases to a pre-set level, the valve functions as a conventional relief valve. The compensating pressure varies across different ranges: 45 psi (3 bar) for the A range, 30 psi (2 bar) for the B range, and 100 psi (7 bar) for the C range. The performance curve of this valve highlights system pressure on the X axis and the pressure differential it creates across the control orifice on the Y axis. The curves illustrate various bypass flows, defined as pump flow minus control flow, which determine the valve's capacity and performance; control flow is not considered in this evaluation. The valve has a capacity of 10 gpm (40 L/min) and can operate at a maximum pressure of up to 5000 psi (350 bar). It features a typical response time of 10 ms and maintains maximum leakage of 2 in/min at 110 SUS (24 cSt). The adjustment for increasing settings involves turning clockwise up to five full turns. Installation specifications include a valve hex size of .78 inches (22.2 mm), with installation torque requirements between 30-35 lbf ft (41-47 Nm). The model weighs .40 lb (.20 kg) and utilizes Viton seals with an available seal kit under cartridge number 990011006.
