characteristics. The valve does not incorporate the use of dynamic seals; this reduces noise, improves reseat characteristics, and further provides for very low hysteresis. This lack of internal seals also assures very low overshoot of the pressure setting (9.5 percent at 5000 psi) and minimal response time of 40msec. The RVD50-20 has six spring ranges with settings up to 5000 psi to ensure precise differential relief specific to the machine and allows the valve to operate with low pressure rise... (read more) -

valves regulate return flow to tank, and the EPFR provides excess flow unloading. Flow not required by the cylinder is vented to tank at load pressure (plus spring value) rather than relief valve pressure, improving system efficiency and reducing heat. The RV08-29 relief valve is used to set maximum system operating pressure. When the valve setting is reached, pilot flow is vented allowing the EPFR to bypass pump flow to tank. The small RV08-29 is used in place of a separate high-flow relief... (read more)
