The Sun Hydraulics RVGTLCV (RVGTLCV) 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 enables remote control by other pilot or 2-way valves. The adjust screw allows for setting both the maximum relief and minimum threshold settings. The valve is immune to cavitation-related issues such as noise and manifold erosion due to its internal modulating design. It can handle maximum pressure at port 2, making it suitable for cross-port relief circuits but not for load-holding applications. When pressure at inlet port 1 surpasses the threshold, the valve opens to tank port 2, with the pilot section incrementally increasing the setting by compressing the spring until it reaches a mechanical stop. This valve provides protection for hydrostatic drives by reducing jerkiness during sudden reversals and is applicable in cross-port applications. With a switching device, it can offer ramp characteristics similar to proportional valves. It also extends pump life by allowing small power units to start against an anti-shock relief. Back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio, while its main stage orifice is contamination-protected. The Sun floating style construction minimizes internal part binding risks. Key specifications include a cavity type T-17A series with a capacity of up to 60 gpm (240 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 2 ms. The adjustment mechanism allows for up to 4.5 clockwise turns for setting increases, and installation requires specific torque values detailed in its technical specifications. The model weighs approximately 1.60 lb (0.70 kg) and uses Viton seal kits like the cartridge model number 990217006 for maintenance purposes.

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.
