The Sun Hydraulics RVGTCWN (RVGTCWN) is a ventable, pilot-operated, anti-shock relief cartridge designed to limit maximum system pressure and control the rate of pressure rise. This three-port valve features a vent port that allows for remote control by other pilot or two-way valves. The adjustable screw sets both the maximum relief and minimum threshold settings. Inside the cartridge, modulating occurs to prevent issues like cavitation noise and manifold erosion. This 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 moving forward to increase the setting until a mechanical stop is reached. It helps protect hydrostatic drives by reducing jerks from sudden reversals and can mimic ramp characteristics of proportional valves when used with a switching device. The valve also extends pump life in small power units by starting against an anti-shock relief. Back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio, and its main stage orifice is contamination-protected. The Sun floating style construction minimizes internal part binding due to excessive installation torque or machining variations. With a capacity of 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model has factory pressure settings established at 4 gpm (15 L/min). It features a response time of approximately 2 ms and an adjustment mechanism that requires 4.5 clockwise turns to increase settings. The RVGTCWN comes with Viton seals in its cartridge seal kit (990217006) and weighs approximately 1.60 lb (0.70 kg).

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.
