Product Information PRESSURE VALVE Pilot-Operated,Spool-type, Relief Valve Type: RV16-S6 Max. operating pressure: 250 bar (3600 psi) Proof pressure: 375 bar (5500 psi) Flow: 300 L/min Description RV16-S6 is a screw-in, two stage pilot-operated,spool-type cartridge relief valve, applied as a pressure control device for hydraulic circuits with high demanding on fast response and low hysteresis. Operation The RV16-S6A blocks flow from ® to © , until sufficient pressure is applied at ® to force the pilot relief off its seat. The pilot flow cause the pressure differential across the main spool,resulting in the valve shift and flow opening from ® to © . The RV16-S6A offers fast response to load changes in hydraulic circuits. Note: Back pressure at © will increase the pilot pressure required at © to shift, at a ratio of 1:1. The RV16-S6A cannot be used in crossover relief applications.
