The Sun Hydraulics RVGELBV (RVGELBV) is a fast-acting, ventable, pilot-operated, balanced piston relief cartridge designed as a normally closed pressure regulating valve. This model opens to tank port 2 when the inlet port 1 pressure reaches the valve setting, throttling flow to regulate pressure. It features a vent port (port 3) for remote control using other pilot or 2-way valves. Known for its low pressure rise versus flow and rapid response time of approximately 2 milliseconds, this valve is suitable for applications requiring quick adjustments and precise control. The RVGELBV can handle maximum pressures at port 2 and is appropriate for cross-port relief circuits, although spool leakage should be considered in such configurations. The main stage orifice is safeguarded by a 150-micron stainless steel screen; however, it is not recommended for load-holding applications due to potential spool leakage. The back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. It incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations. This model fits into cavity T-17A series with a capacity of up to 60 gpm (240 L/min) and operates under a maximum pressure of 5000 psi (350 bar). It requires an installation torque of 150-160 lbf ft (203-217 Nm), with adjustment settings managed via an internal hex screw and secured by a locknut torqued at 80-90 lbf in (9-10 Nm). The RVGELBV weighs approximately 1.60 lb (0.70 kg) and uses Viton seal kits for robust performance in various conditions.
