The Sun Hydraulics RPITLCV (Material Number: RPITLCV) is a pilot-operated, anti-shock relief cartridge designed to limit maximum system pressure and control the rate of pressure rise. This valve effectively opens and ramps closed at a constant speed, independent of settings and flows, with an adjustable screw to determine both maximum relief and minimum threshold settings. It is physically and functionally interchangeable with all 2-port relief cartridges except pilot reliefs, sharing the same flow path and cavity for a given frame size. The valve can accept 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 setting, the valve opens to tank port 2, providing protection against pressure transients due to sudden load changes, especially in variable displacement pumps. It also helps reduce jerk caused by sudden reversals in hydrostatic drives. The RPITLCV can be used with a switching device to provide ramp characteristics similar to proportional valves and allows small power units to start against an anti-shock relief for longer pump life. With back pressure on tank port 2 directly additive to the valve setting at a 1:1 ratio, this valve incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. Additional specifications include a capacity of 100 gpm (380 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 2 ms, and adjustment capability with four-and-a-half clockwise turns needed to increase settings. The valve has specific installation torque requirements and comes with a Viton seal kit option for enhanced durability.

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. The adjust screw determines the maximum (relief) setting and the minimum (threshold) setting.
- All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- 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 pumps and motors from pressure transients due to sudden load changes, especially variable displacement pumps, since the displacement mechanism is sometimes too slow to catch these pressure transients.
- 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.
- 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.
