The Sun Hydraulics RVGTCWV (Material Number: RVGTCWV) 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. The adjust screw controls both the maximum relief setting and the minimum threshold setting. Inside the cartridge, modulating occurs to make these valves resistant to cavitation issues such as noise and manifold erosion. The valve accepts maximum pressure at port 2, making it suitable for cross-port relief circuits but not for load-holding applications. When inlet port 1 pressure exceeds the threshold, the valve opens to tank port 2 with a steady ramp-up of settings due to pilot spring compression until a mechanical stop is reached. The RVGTCWV provides protection for hydrostatic drives by reducing sudden reversal jerks and can be used in cross-port applications. It can also offer ramp characteristics typically provided by proportional valves when used with a switching device. Additionally, small power units can be started against an anti-shock relief to extend pump life. The back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. It incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or machining variations. Specifications include a cavity T-17A, series 3 capacity of up to 60 gpm (240 L/min), and a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 15-20 in\u00b3/min (0.25-0.33 L/min), with typical response times around 2 ms and pressure ramp-up times between 300-500 ms. The adjustment requires approximately 4.5 clockwise turns to increase settings, with specific torque requirements for installation and adjustment components provided in detail.

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.
