The Sun Hydraulics RVETCCV (RVETCCV) is a ventable, pilot-operated anti-shock relief cartridge designed to limit maximum system pressure and control the rate of pressure rise. This advanced hydraulic component features a three-port design with a vent port (port 3) that facilitates remote control via other pilot or two-way valves. The valve's adjust screw allows for precise setting of maximum relief and minimum threshold levels, ensuring optimal performance in various applications. One of its standout features is its immunity to cavitation-related issues such as noise and manifold erosion, thanks to the modulating action occurring within the cartridge itself. The RVETCCV can handle maximum pressure at port 2, making it ideal for cross-port relief circuits. However, it is not suitable for load-holding applications. When inlet port 1 pressure surpasses the threshold setting, the valve opens to tank port 2, with the pilot section steadily moving forward to compress the pilot spring until it reaches a mechanical stop for maximum setting. This valve provides critical protection for hydrostatic drives by reducing jerks from sudden reversals and is well-suited for cross-port applications. When paired with a switching device, it offers ramp characteristics similar to those provided by proportional valves. It also extends pump life by allowing small power units to start against an anti-shock relief. The valve's main stage orifice is contamination-protected, and its construction minimizes internal part binding due to installation torque or machining variations. Key specifications include a capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), and response time of approximately 2 ms, with factory settings established at 4 gpm (15 L/min).

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.
