The Sun Hydraulics RVITLCN (RVITLCN) is a ventable, pilot-operated, anti-shock relief cartridge designed to limit maximum system pressure and control the rate of pressure rise. This valve is engineered to open and ramp closed at a constant speed, independent of settings and flows. It features a vent port (port 3) for remote control by other pilot or 2-way valves. The adjust screw on this valve determines both the maximum relief setting and the minimum threshold setting. Notably, these valves are immune to issues like noise and manifold erosion due to cavitation because modulating occurs inside the cartridge. The RVITLCN can handle maximum pressure at port 2, making it suitable for cross-port relief circuits but not for load-holding applications. When the inlet port 1 pressure exceeds the threshold setting, the valve opens to tank port 2, with its pilot section moving forward steadily to increase settings by compressing the pilot spring until a mechanical stop is reached. This valve offers protection for hydrostatic drives by minimizing jerks caused by sudden reversals, making it ideal for cross-port applications. It can be combined with switching devices to provide ramp characteristics similar to those offered by proportional valves. Additionally, small power units can start against an anti-shock relief provided by this valve to extend pump life. Back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. The main stage orifice is protected against contamination, and its floating style construction minimizes internal parts binding due to excessive installation torque or machining variations in cavity/cartridge setups. With a capacity of 120 gpm (480 L/min), maximum operating pressure of 5000 psi (350 bar), and factory pressure settings established at 4 gpm (15 L/min), this model ensures reliable performance across demanding applications.

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.
