To increase the pressure, turn the handle clockwise gradually. To reduce the pressure, turn it counterclockwise.After pressure adjustment, be sure to tighten the lock nut.■RV-13Maximum operating pressureMPaModelRV-1370RV-14Internal pilotExternal pilotControl Valves■TCB-8Connection port sizeRc3/82 to 101/23/810 to 701/2Allowable back pressureMPaConnection port sizeRcNo.79E since2025Approx. weightkg3.53.88.53.53.88.5fully openApprox. weightkg■Hydraulic symbol 3/81.61/2Maximum flow rateL/minPressure adjustable rangeMPa204080204080Maximum flow rateL/minPressure adjustable rangeMPa10 to 7010109
