The Sun Hydraulics RVESLWN (RVESLWN) is a ventable, pilot-operated, balanced poppet relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to tank port 2 when the inlet port 1 pressure reaches the set level, thereby regulating flow and maintaining desired pressure levels. It features a vent port (port 3) that allows for remote control via other pilot or two-way valves, making it suitable for load-holding applications as long as any valving on the vent port is zero leak. The RVESLWN is engineered to handle maximum pressures at port 2 and can be used in cross-port relief circuits. This valve's design ensures accuracy with minimal pressure rise versus flow, offering smooth and quiet operation with moderate response speed. The internal modulation within the cartridge effectively mitigates cavitation issues such as noise and manifold erosion. Additionally, the valve remains relatively insensitive to changes in oil temperature and contamination, thanks to its robust construction that includes a main stage orifice shielded by a 150-micron stainless steel screen. The RVESLWN accepts back pressure on tank port 2 at a direct 1:1 additive ratio to the valve setting and incorporates Sun's floating style construction to prevent internal binding due to installation torque or machining variations. It has a capacity of 25 gpm (95 L/min), operates up to a maximum pressure of 5000 psi (350 bar), and features an adjustment mechanism that increases setting with clockwise turns. Installation requires specific torque values for optimal performance, ensuring this cartridge is both reliable and durable in demanding hydraulic environments.
