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.■ SpecificationsMaximum operating pressureMPaMaximum flow rate L/minModel0 to 8 MPa8 to 70 MPaERV-P70ERV-AERV-B■ERV-P ■ESW-4H･P･C■ESW-4HMaximum flow rate L/min0 to 8 MPa8 to 70 MPa631631PABllllDllill (ESL-4P)Pressure adjustable rangeMPa10 to 70■Hydraulic symbol (ERV-A)Bolt insertion lengthmmAccessoryO-rings: P8 (4 pcs)10Approx. weightkg1.5136
