The Sun Hydraulics RVGTCAV (Material Number: RVGTCAV) is a ventable, pilot-operated, anti-shock relief cartridge designed to limit maximum system pressure and control the rate of pressure rise. This valve features a unique mechanism that opens and then ramps closed at a consistent speed, independent of settings and flow rates. It includes three ports, with a vent port (port 3) situated between the main piston and the pilot stage for remote control by other pilot or two-way valves. The adjust screw allows for setting both maximum relief and minimum threshold pressures. This valve is particularly suited for cross-port relief circuits as it can handle maximum pressure at port 2. However, it is not recommended for load-holding applications. The RVGTCAV provides protection for hydrostatic drives by reducing sudden reversals' jerkiness and can be used with switching devices to offer ramp characteristics similar to those of proportional valves. Additionally, small power units can benefit from starting against an anti-shock relief to extend pump life. The valve's design ensures immunity to cavitation-related issues such as noise and manifold erosion due to its internal modulating process. It incorporates Sun's floating style construction, minimizing potential binding of internal parts due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a capacity of 60 gpm (240 L/min), maximum operating pressure of 5000 psi (350 bar), and a typical response time of 2 ms. The factory pressure settings are established at 4 gpm (15 L/min), with an adjustment range achieved through 4.5 clockwise turns. It features robust construction with a valve hex size of 1-1/4 in. (31.8 mm) and is installed with a torque range of 150-160 lbf ft (203-217 Nm). The model weighs approximately 1.60 lb (0.70 kg) and includes Viton seal kits available under part number 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.
