Technical characteristics • The combination of this two functions ensures that the downstream pressure is maintained in case of accidental loss of supply pressure and at the same time grants the possibility to regulate the circuit flow rate. A typical application of this combination is close to or directly assembled onto the actuator connection ports. This allows to keep pressurised the cylinder chamber in case of accidental loss of supply pressure and to regulate the exhaust flow rate when the blocking valve is actuated. • The possible combinations are the following: - Unidirectional blocking valve + unidirectional flow control valve - Bidirectional blocking valve + bidirectional flow control valve - Bidirectional blocking valve + unidirectional flow control valve - Unidirectional blocking valve + bidirectional flow control valve Technical characteristics • Fluid: Filtered and lubricated air or non • Working ports size: see connections list • Max working pressure: 0,5 ... 10 bar • Temperature: -5 °C ... + 50 °C • Orifice size: Ø3 mm • Flow rate at 6 bar with Δp=1 (Nl/min): 285 Nl/min • Weight: 62 g Note Example: 551.1F1.00.00.XX In line blocking valve + flow control valve.
