In the opposite direction, the flow control valve is bypassed by the non-return valve. – Actuation: Manual – Integrated non-return valve – Operating pressure: 6 MPa (60 bar) – Maximum permissible pressure: 12 MPa (120 bar) – Low-leakage, self-sealing coupling nipples/socket Order no. 152843 3 Non-return valve The valve is closed by a closing cone which is pressed against the seat by a spring. If the valve opening pressure on the seat side is exceeded, the valve opens and the flow can pass through. If the pressure on the spring side is greater, the valve remains closed. – Actuation: Hydraulic – Tube length: 1000 mm – Operating pressure: 6 MPa (60 bar) – Maximum permissible pressure: 12 MPa (120 bar) – Low-leakage, self-sealing coupling sockets 0.05 MPa valve opening pressure Order no. 548617 0.6 MPa valve opening pressure Order no. 548618 4 4 Shut-off valve The valve can be closed by turning the lever. A ball is pressed onto the seal facing away from the pressure and shuts off the flow of volumetric oil without leakage. – Actuation: Manual – Operating pressure: 6 MPa (60 bar) – Maximum permissible pressure: 12 MPa (120 bar) – Low-leakage, self-sealing coupling nipples/socket Order no. 152844 5 Non-return valve, piloted The valve is closed by a closing cone which is pressed against the seat by a spring. The closing cone only opens when X is opened. If the valve opening pressure on the seat side is exceeded, the valve opens and the flow can pass 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. 544339 6 Double non-return valve, piloted The two non-return valves are each unlocked from the opposite side. – Area ratio of control piston to non-return valve seat 3.3:1 – 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. 572151 5 6 2
