The Sun Hydraulics RVGBKCN (Material Number: RVGBKCN) is a versatile three-port normally closed modulating element with relief capabilities. This component integrates two critical functions when used with an external orifice. Primarily, it acts as a bypass compensator, regulating a priority flow into the circuit as determined by the external orifice, while any excess input flow is redirected to tank port 2. Moreover, if the pressure at inlet port 1 exceeds the valve's set threshold, it functions as a standard relief valve. The compensating pressure across all ranges is maintained at 120 psi (8 bar). The performance curve of this valve illustrates how system pressure (X-axis) influences the pressure differential across the control orifice (Y-axis), with various curves depicting different bypass flows. Importantly, the valve's capacity and performance are dictated by bypass flow rather than control flow. This model fits a T-17A cavity and belongs to Series 3, offering a capacity of up to 40 gpm (160 L/min). It operates under a maximum pressure of 5000 psi (350 bar) and typically responds within 10 milliseconds. Valve leakage is minimal at specified conditions, ensuring efficient operation. The adjustment mechanism allows for fine-tuning with up to 5.5 clockwise turns needed to increase settings. Installation specifications include a valve hex size of 1-1/4 inches (31.8 mm) and an installation torque range between 150-160 lbf ft (203-217 Nm). The internal hex size for adjustment screws is 5/32 inches (4 mm), while the locknut requires a hex size of 9/16 inches (15 mm) and torque between 80-90 lbf in (9-10 Nm). Weighing in at approximately 1.60 lb (0.70 kg), this model also includes a Viton seal kit designated as Cartridge: Viton: 990017006 for reliable sealing performance in various applications.
