The Sun Hydraulics RVETLBV (Material Number: RVETLBV) is a ventable, pilot-operated, anti-shock relief cartridge designed to limit maximum system pressure and control the rate of pressure rise. This advanced valve features a unique design where it opens and ramps closed at a constant speed, independent of settings and flows. It includes a vent port (port 3) between the main piston and pilot stage for remote control by other pilot or 2-way valves. The adjust screw allows for setting both maximum relief and minimum threshold pressures. Notably, the cartridge's modulating action makes it resistant to cavitation issues such as noise and manifold erosion. This valve is suitable for cross-port relief circuits, accepting maximum pressure at port 2. However, it is not recommended for load-holding applications. In operation, when the inlet port (port 1) exceeds the threshold setting, the valve opens to tank port (port 2), with the pilot section moving forward steadily to increase setting by compressing the pilot spring until a mechanical stop is reached. The RVETLBV provides hydrostatic drive protection by reducing jerks from sudden reversals and can be used with switching devices to mimic ramp characteristics typically offered by proportional valves. Ideal for small power units started against an anti-shock relief to prolong pump life, this valve features back pressure on tank port 2 that directly adds to its setting in a 1:1 ratio. Its main stage orifice is protected against contamination and employs Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. Specifications include a capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 2 ms, and adjustment capabilities with four-and-a-half clockwise turns to increase settings.

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.
