The Sun Hydraulics RVEBUCN (RVEBUCN) is a three-port normally closed modulating element with relief, offering dual functionalities when paired with an external orifice. This hydraulic component acts as a bypass compensator, effectively managing priority flow into a circuit based on the external orifice's specifications. Any input flow exceeding the designated priority flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve's set threshold, it functions as a standard relief valve. The compensating pressure for all ranges is standardized at 120 psi (8 bar). The performance curve of this valve illustrates system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis, highlighting various bypass flows where pump flow minus control flow determines capacity and performance. The RVEBUCN model allows adjustments through W and Y controls, with or without special settings, enabling full-range adjustability unless specified otherwise. Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Typical response time is approximately 10 ms, and maximum valve leakage under specified conditions is 3 in\u00b3/min (50 cc/min). Installation details include a valve hex size of 1 1/8 in. (28.6 mm) and torque requirements between 45-50 lbf ft (61-68 Nm). The adjustment screw features an internal hex size of 5/32 in. (4 mm), with locknut torque set between 80-90 lbf in. (9-10 Nm). The model weighs .70 lb (.30 kg) and utilizes Viton seal kits for optimal performance and durability in various applications.
