The Sun Hydraulics RVITCWN (RVITCWN) is a ventable, pilot-operated, anti-shock relief cartridge designed to limit both the maximum system pressure and the rate of pressure rise. This valve opens and then ramps closed at a constant speed, independent of settings and flows. It features a vent port (port 3) that connects between the main piston and the pilot stage for remote control by other pilot or 2-way valves. The adjust screw allows for setting both maximum relief and minimum threshold levels. Due to its internal modulation, this cartridge is resistant to cavitation-related issues such as noise and manifold erosion. 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 moving forward at a steady rate until reaching a mechanical stop. The valve provides protection for hydrostatic drives by reducing jerks from sudden reversals and is apt for cross-port applications. With a switching device, it can offer ramp characteristics similar to proportional valves. Small power units benefit from longer pump life when started against an anti-shock relief setting. The back pressure on tank port 2 adds directly to the valve setting in a 1:1 ratio, while its main stage orifice is safeguarded against contamination. The Sun floating style construction minimizes potential binding from excessive installation torque or cavity/cartridge machining variations. This model fits into Cavity T-19A Series 4 with a capacity of up to 120 gpm (480 L/min) and operates under pressures up to 5000 psi (350 bar). Its response time averages around 2 ms with pressure ramp-up times between 400-850 ms. Installation specifications include a valve hex size of 1-5/8 inches (41.3 mm) and an installation torque of 350-375 lbf-ft (474-508 Nm).

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.
