The Sun Hydraulics RVIBLBN (Material Number: RVIBLBN) is a versatile three-port normally closed modulating element with relief capabilities, designed for integration with an external orifice. This component functions primarily as a bypass compensator, regulating priority flow within a circuit while redirecting excess input flow to the tank port. It also acts as a conventional relief valve when inlet pressure surpasses the predefined setting. Notably, the compensating pressure is set at 90 psi (6 bar), and the valve's performance is influenced by bypass flow rather than control flow. Key specifications include a maximum operating pressure of 5000 psi (350 bar) and a typical response time of 10 ms. The valve has an impressive capacity of up to 80 gpm (320 L/min) and demonstrates minimal leakage, with a maximum rate of 5 in\u00b3/min at 110 SUS (24 cSt). It features EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. Installation requires specific torque settings, with a hex size of 1-5/8 inches (41.3 mm) for the valve and adjustments made via an internal hex size of 5/32 inches (4 mm). The product's robust construction ensures durability, weighing in at 3.10 lb (1.40 kg), and it comes with options such as Viton seal kits for enhanced performance under varied conditions. This model is ideal for applications requiring precise flow regulation and pressure relief in hydraulic systems, offering reliable performance across diverse operational environments.
