Order no. 193972 2 Non-return valve – Standard nominal flow rate: 136 l/ min – Push-in fitting connection for plastic tubing with O.D. 4 mm. Order no. 153462 3 Non-return valve, piloted As long as there is a control signal at the non-return valve, the compressed air flows to and from the cylinder. If the control signal is removed, the non-return valve blocks the cylinder exhaust air and thus stops the cylinder movement. The valve can be used for positioning and braking functions. – Operating pressure: 50 – 1000 kPa (0.5 – 10 bar) – Standard nominal flow rate: 108 l/ min Order no. 540715 1 3 2 4 5 6 4/5/6 One-way flow control valve The one-way flow control valve is a combination of a flow control valve and a non-return valve. The throttle cross-section can be adjusted with a knurled screw. – Pressure range: 20 – 1000 kPa (0.2 – 10 bar) – Standard nominal flow rate: – In the flow control direction: 0 – 85 l/min – Against the flow control direction: 100 – 110 l/min Order no. 193967 5 One-way flow control valve – Quick-action mounting system Quick-Fix Order no. 560159 6 One-way flow control valve – Quick-action mounting system Quick-Fix Order no. 152881
