The Sun Hydraulics RVISLBV (RVISLBV) is a ventable, pilot-operated, balanced poppet relief cartridge designed to regulate pressure in hydraulic systems. This valve remains normally closed until the inlet port pressure reaches the pre-set level, at which point it opens to throttle flow to the tank port, thereby managing system pressure. Notably, it features a vent port that allows for remote control by other pilot or two-way valves. The RVISLBV is known for its accuracy and low pressure rise versus flow characteristics, offering smooth and quiet operation with moderate response speed. It is particularly suitable for load-holding applications provided that any valving on the vent port is zero leak. This cartridge valve can handle maximum pressure at the tank port and is apt for cross-port relief circuits. It also allows a remote pilot relief on the vent port to control the valve below its set pressure. The design ensures insensitivity to varying oil temperatures and contamination, thanks in part to a 150-micron stainless steel screen protecting the main stage orifice. The backpressure on the tank port directly adds to the valve setting at a 1:1 ratio. Incorporating Sun's floating style construction, this valve minimizes binding issues due to installation torque or machining variations. It operates within a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 120 gpm (480 L/min). With factory settings established at 4 gpm (15 L/min), it offers reliable performance with minimal leakage. The model weighs approximately 3.10 lb (1.40 kg) and includes options for Viton seal kits for enhanced durability in various applications.
