The oil flows from B to A via the opening non-return valve. – Actuation: Manual – Differential pressure of the pressure balancer: 0.55 MPa (5.5 bar) – Operating pressure: 6 MPa (60 bar) – Maximum permissible pressure: 12 MPa (120 bar) – Low-leakage, self-sealing coupling nipples – Quick-action mounting system Quick-Fix Order no. 544338 2 3-way flow control valve The valve ensures a constant volumetric flow rate in the direction of flow from P to A, regardless of the load pressure on A. The excess volumetric flow rate is diverted via B and can be supplied to another consumer. The excess volumetric flow rate is diverted via B and can be supplied to another consumer. – Actuation: Manual – Differential pressure of the pressure balancer: 0.55 MPa (5.5 bar) – Operating pressure: 6 MPa (60 bar) – Maximum permissible pressure: 12 MPa (120 bar) – Low-leakage, self-sealing coupling nipples – Quick-action mounting system Quick-Fix Order no. 572150 3 Flow divider The valve divides the volumetric flow rate to A and B at a ratio of 50:50, independently of the load. – Actuation: Hydraulic – Minimum flow rate: 0.5 l/min – Operating pressure: 6 MPa (60 bar) – Maximum permissible pressure: 12 MPa (120 bar) – Valve connection diagram, hydraulic ISO/DIN 4401 size 02 – Low-leakage, self-sealing coupling nipples – Quick-action mounting system Quick-Fix Order no. 544340 4 Shuttle valve The shuttle valve is switched through to the output by pressurizing one of the two inputs (OR function). If both inputs are pressurized, the higher pressure is switched through. – Actuation: Hydraulic – Operating pressure: 6 MPa (60 bar) – Maximum permissible pressure: 12 MPa (120 bar) – Low-leakage, self-sealing coupling nipples – Quick-action mounting system Quick-Fix Order no. 572122 5 Priority valve LS, dynamic The valve supplies the flow direction from P to CF preferentially and independently of the load pressure on CF. The excess volume flow is diverted via EF and fed to another consumer. – Actuation: Hydraulic – Differential pressure of the pressure balancer: 1.03 MPa (10.3 bar) – Operating pressure: 6 MPa (60 bar) – Maximum permissible pressure: 12 MPa (120 bar) – Low-leakage, self-sealing coupling nipples – Quick-action mounting system Quick-Fix Order no. 573022 1 2 3 4 5
