The flow control screws enable the flow rate to be continuously adjustment in either flow direction. In the reverse direction, the air flows through a non-return valve with full cross-section. – Pneumatic connection, via push-in fitting for plastic tubing with O.D. 4 mm. – Standard nominal flow rate in flow control/non-return direction: 90/70 l/min Order no. 548634 2 Quick-exhaust valve Quick-exhaust valve, with integrated silencer. – Design: Poppet valve – Standard nominal flow rate: 1 – 2; 2 – 3: 300 l/min; 390 l/min Order no. 539772 3 Pneumatic resistor, long The component functions as a pneumatic resistor. Thanks to the small diameter and long length of the tubing, the two key features of pneumatic tubing and how they affect the flow rate and system behavior can be examined. – Tubing diameter: O.D. 2 mm – Tube length: 12 m – Pneumatic connection, via push-in fitting for plastic tubing with O.D. 4 mm. – Quick-action mounting system Quick-Fix Order no. 4646991 4 Pneumatic resistor, short The component functions as a pneumatic resistor. Thanks to the small tubing diameter, the effects on the volumetric flow rate and system behavior can be examined. – Tubing diameter: O.D. 2 mm – Tube length: 10 cm – Pneumatic connection, via push-in fitting for plastic tubing with O.D. 4 mm. Order no. 4809992 1 3 4 2
