The Sun Hydraulics RVESLNV (RVESLNV) is a ventable, pilot-operated, balanced-poppet relief cartridge designed for precise pressure regulation in hydraulic systems. This valve remains normally closed until the inlet port pressure reaches the set value, at which point it opens to the tank port to throttle flow and maintain the desired pressure. A vent port is included to allow for remote control via other pilot or 2-way valves. Known for their accuracy and low noise operation, these valves are suitable for load-holding applications provided that any valving on the vent port is zero leak. The RVESLNV can handle a maximum operating pressure of 5000 psi and features a main stage orifice protected by a 150-micron stainless steel screen to guard against contamination. This model incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. The valve's performance remains stable across varying oil temperatures and contamination levels, making it robust in diverse conditions. Additionally, back pressure on the tank port directly influences valve settings at a 1:1 ratio, ensuring consistent performance. The RVESLNV has a capacity of 25 gpm (95 L/min) and requires an installation torque between 45-50 lbf ft. With its relatively fast response time of approximately 2 ms and minimal leakage at reseat (10 drops/min), this valve is reliable for applications requiring precise pressure control. The adjustment mechanism allows for easy setting changes with five clockwise turns needed to increase pressure settings, complemented by secure locking capabilities through its locknut design.
