The Sun Hydraulics RVGTCBN (RVGTCBN) is a ventable, pilot-operated, anti-shock relief cartridge designed to limit maximum system pressure and control the rate of pressure rise. This 3-port valve features a vent port that allows for remote control by other pilot or 2-way valves. Its design ensures immunity from cavitation-related issues such as noise and manifold erosion. The valve can handle maximum pressure at port 2, making it suitable for cross-port relief circuits but not for load-holding applications. When inlet port 1's pressure surpasses the threshold setting, the valve opens to tank port 2, with the pilot section increasing the setting steadily until a mechanical stop is reached. It offers protection for hydrostatic drives by reducing jerk during sudden reversals and can mimic ramp characteristics when paired with a switching device. The valve supports small power units starting against an anti-shock relief, extending pump life. Back pressure on tank port 2 is directly additive to the valve setting at a 1:1 ratio. The main stage orifice is contamination-protected, and Sun's floating style construction minimizes internal part binding risks due to installation torque or machining variations. The RVGTCBN operates within a cavity T-17A/Series 3 with a capacity of up to 60 gpm (240 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It has a typical response time of 2 ms and takes between 300-500 ms for pressure ramp-up. The adjustment screw requires approximately 4.5 clockwise turns to increase settings, with specific dimensions provided for installation torque and hex sizes. The model weighs approximately 1.60 lb (0.70 kg) and includes Viton seal kit options (990217006).

Ventable, pilot-operated, anti shock relief cartridges limit maximum system pressure and also limit the rate of pressure rise. The valve opens and then ramps closed at a constant speed, independent of settings and flows. These 3 port valves include a vent port (port 3) that connects between the main piston and the pilot stage to provide for remote control by other pilot or 2-way valves. The adjust screw determines the maximum (relief) setting and the minimum (threshold) setting.
- Because the modulating occurs inside the cartridge, these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- A remote pilot relief on port 3 (vent) will control the valve below its own setting.
- Not suitable for use in load holding applications.
- When pressure at the inlet (port 1) exceeds the threshold setting, the valve opens to tank (port 2). The pilot section moves forward at a steady rate, increasing the setting by compressing the pilot spring. Maximum setting is achieved when the pilot section reaches a mechanical stop.
- Valve provides protection for hydrostatic drives by reducing the jerk caused by sudden reversals. The valve is suitable for cross-port applications.
- When used with a switching device, the valve can provide the ramp characteristic typically provided by proportional valves.
- Small power units can be started against an anti shock relief to provide longer pump life.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- The main stage orifice is protected against contamination.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
