The Sun Hydraulics RVGDLAN (RVGDLAN) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed to function as a normally closed pressure regulating valve. This robust component begins to open at the tank port 2 when the inlet port 1 pressure reaches the set threshold, thereby throttling flow to maintain regulated pressure. It features a vent port 3 for remote control via other pilot or two-way valves and a drain port 4 that ensures insensitivity to back pressure. These valves are noted for their accuracy, smooth operation, moderate speed, and low noise levels. The RVGDLAN valve is capable of handling maximum pressures at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. Its main stage orifice is shielded by a 150-micron stainless steel screen; however, this valve is not recommended for load-holding applications due to spool leakage. The pressure at port 4 directly adds to the valve setting in a 1:1 ratio but should not exceed 5000 psi (350 bar). The floating style construction minimizes internal binding risks due to excessive installation torque or machining variations. With a cavity T-23A series and capacity of up to 60 gpm (240 L/min), factory pressure settings are established at 4 gpm (15 L/min). The valve's maximum operating pressure is capped at 5000 psi (350 bar), with control pilot flow between 15 - 20 in\u00b3/min (0.25 - 0.33 L/min) and typical response time around 10 ms. Maximum leakage stands at approximately 4 in\u00b3/min under specific conditions. The RVGDLAN boasts features like adjustment screw internal hex size of ^5/32 inch and locknut torque ranging from 80 -90 lbf\u00b7in (9 \u201310 Nm), ensuring precise adjustments and secure installations.
