The Sun Hydraulics RVEBUAV (RVEBUAV) is a three-port normally closed modulating element with relief capabilities, designed to provide dual functions when paired with an external orifice. This valve primarily acts as a bypass compensator, regulating priority flow into the circuit as dictated by the external orifice, while directing surplus input flow to the tank port. Additionally, it operates as a standard relief valve if the inlet pressure surpasses the set threshold. The compensating pressure for all ranges is maintained at 120 psi (8 bar). The performance of this valve is influenced by bypass flow, which is calculated as pump flow minus control flow; control flow itself does not affect capacity or performance. The RVEBUAV model offers adjustable settings throughout its complete range via W or Y controls unless a specific setting is predetermined, in which case it denotes the maximum setting possible. It features a T-2A cavity series with a capacity of 20 gpm (80 L/min), and can withstand a maximum operating pressure of 5000 psi (350 bar). Typical response time for this model is approximately 10 milliseconds, with maximum valve leakage rated at 3 cubic inches per minute at 1000 psi (50 cc/min at 70 bar) when using oil with viscosity of 110 SUS (24 cSt). The adjustment mechanism requires up to five clockwise turns to increase settings and includes an internal hex size of 5/32 inches for the adjustment screw. Installation torque for this valve ranges from 45 to 50 lbf-ft (61 to 68 Nm), and it weighs approximately .70 lb (.30 kg). For maintenance, a Viton seal kit is available under part number 990202006.
