The Sun Hydraulics RVCSLWV (RVCSLWV) is a ventable, pilot-operated, balanced-poppet relief cartridge designed to regulate pressure by opening to tank port 2 when inlet port 1 reaches the valve setting. This sophisticated valve features a vent port (port 3) for remote control via other pilot or two-way valves, ensuring precise pressure regulation with minimal noise and erosion due to cavitation. Notably accurate and smooth in operation, it accepts maximum pressure at port 2, making it suitable for cross-port relief circuits and load-holding applications. The valve's performance is resilient to variations in oil temperature and contamination, thanks to its robust design that includes a main stage orifice protected by a 150-micron stainless steel screen. The RVCSLWV incorporates Sun's floating style construction, reducing the risk of internal binding from installation torque or machining variations. It can handle a maximum operating pressure of 5000 psi (350 bar) with a capacity of 15 gpm (60 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with response times typically around 2 ms. The valve's adjustment allows for up to five clockwise turns to increase settings, featuring an internal hex screw size of 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm), requiring a torque of 80-90 lbf-in (9-10 Nm). Weighing just .35 lb (.15 kg), this cartridge is compact yet highly effective in managing hydraulic systems. It should be noted that cartridges configured with EPDM seals are intended for phosphate ester fluids only; exposure to petroleum-based substances will damage these seals.
