The Sun Hydraulics RVITCWV (Material Number: RVITCWV) is a ventable, pilot-operated, anti-shock relief cartridge designed to limit maximum system pressure and control the rate of pressure rise. This sophisticated 3-port valve features a vent port that allows for remote control by other pilot or 2-way valves, making it ideal for applications requiring precise pressure modulation and protection against cavitation-induced issues such as noise and manifold erosion. The valve's adjust screw sets the maximum relief and minimum threshold settings, while its internal modulating mechanism ensures consistent performance regardless of flow conditions. Engineered to handle maximum pressure at port 2, the RVITCWV is suitable for cross-port relief circuits but not recommended for load-holding applications. When inlet port 1 pressure exceeds the threshold setting, the valve opens to tank port 2, with the pilot section advancing at a steady rate until reaching a mechanical stop for maximum setting. This feature provides protection in hydrostatic drives by reducing sudden jerks from reversals and can mimic ramp characteristics typical of proportional valves when used with a switching device. The valve supports small power units by starting against an anti-shock relief to extend pump life. It incorporates Sun's floating style construction to prevent internal binding due to installation torque or cavity machining variations. With a capacity of 120 gpm (480 L/min), a maximum operating pressure of 5000 psi (350 bar), and quick response time of approximately 2 ms, this cartridge ensures reliable performance in demanding environments. The main stage orifice is contamination-protected, while backpressure on tank port 2 directly affects valve setting in a 1:1 ratio. The RVITCWV also features easy adjustment capabilities with specific torque requirements for secure installation.
