VC-70-RC4VC-70-RC3VC-70-R3● Quick couplers cannot be connected where pressure remains. Due to changes in ambient temperature, the pressure could increase inside the hose with couplers at both ends or the cylinder, which makes it difficult to connect couplers. In that case, use the pressure elimination accessory (page 175) to removal pressure before connection. (Note) ● After connecting the coupler, turn the sleeve to lock the coupler for preventing detachment. Note. The maximum operating pressure of the pressure elimination accessory is 10.5 MPa.VC-70-N3VC-70-R4Maximum operating pressure70 MPa■ VC-70 series Pressure loss characteristics against flow rates■VC-70 seriesOperating fluid70General hydraulic oilModel code structureVC-70-RC4VC-70-RC3Approx.weight kg0.060.080.060.210.28No.79E since2025VC-70-N3VC-70-R4VC-70-R3Accessory (duster cap)VC-70-R-DCVC-70-N-DCVC-70-RC-DC170● The pressure loss is reduced to 1/5 of that of a conventional model (ROC-13). ● The force required for the coupler insertion is approximately 1/2 of that of a conventional model. ● Self-sealing type that prevents oil leakage. ● Equipped with a lock mechanism to prevent detachment. ● In the series, couplers with a different thread size can be connected to each other. ● A duster cap (made of resin) is attached to all models. ● As an optional extra, an aluminum duster cap and pressure elimination accessory are available.■VC-70 Maximum operating pressureMPaModelVC-70-R3VC-70-R4VC-70-N3VC-70-RC3VC-70-RC4VC-70-R3
