The Sun Hydraulics RVGTCCN (RVGTCCN) is a ventable, pilot-operated, anti-shock relief cartridge designed to manage system pressure and control the rate of pressure increase. This 3-port valve features a vent port that enables remote control via pilot or 2-way valves. The adjust screw allows for setting both maximum relief and minimum threshold pressures. The internal modulation within the cartridge reduces issues like cavitation, noise, and manifold erosion. It can handle maximum pressure at port 2 and is ideal for cross-port relief circuits but not suitable for load-holding applications. When the inlet port pressure surpasses the threshold, the valve opens to tank port 2, with the pilot section increasing settings by compressing the spring until it reaches a mechanical stop. This valve is particularly beneficial in protecting hydrostatic drives by minimizing sudden reversals' jerkiness and can be used with switching devices to mimic ramp characteristics typical of proportional valves. It also aids in extending pump life when starting small power units against an anti-shock relief. Back pressure on tank port 2 directly affects the valve setting at a 1:1 ratio. The main stage orifice is contamination-protected, and its floating style construction minimizes internal binding risks due to installation torque or machining variations. The RVGTCCN fits into a T-17A cavity series with a capacity of up to 60 gpm (240 L/min) and operates at a maximum pressure of 5000 psi (350 bar). 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. Adjustment involves up to 4.5 clockwise turns to increase settings, with specific torque requirements for installation and adjustments detailed for precision use.

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.
