COMPRESSED AIR TECHNOLOGY Steel couplings JWL series 520 – DN 7.8 Order number Models > > > > > Robust and impact resistant HEAVY-DUTY coupling All couplings are pressed to avoid leakage Low pressure loss due to optimized valve system One-handed connection & disconnection possible Nominal flow rate: 1,900 NL/min (at 6 bar inlet pressure and pressure drop 0.6 bar) > Max. operating pressure (p1) / blasting pressure 35 / 150 bar 41202 M 1/2" 41204 Coupling with internal thread F 1/4" 41210 F 3/8" 41212 F 1/2" 41214 Ø 6 mm 41216 Coupling with PUR connection Safety couplings with push button – DN 7.4 > The safety coupling according to ISO 4414, DIN EN 983 with push-button actuation prevents the so-called "whiplash effect" when uncoupling > The rotatable connection (swivel joint) enables the push button to be moved to the most ergonomically favourable position when the couplings are permanently mounted. > Nominal flow rate: 1,600 NL/min (at 6 bar inlet pressure and pressure drop 1 bar) > Max. operating pressure (p1): 12 bar 41200 M 3/8" Coupling with hose nozzle Axis of rotation = 360° M 1/4" Coupling with external thread (incl. PTFE seal) Ø 8 mm 41217 Ø 10 mm 41218 Ø 13 mm 41219 Ø 5x8 mm 41220 Ø 6.5x10 mm 41221 Ø 8x12 mm 41222 Ø 9.5x13.5 mm 41223 Order number Models Safety coupling with external thread Safety coupling with internal thread Safety coupling with hose nozzle AG 1/4“ 42770 M 3/8" 42771 M 1/2" 42772 IG 1/4“ 42773 F 3/8" 42774 F 1/2" 42775 Ø 6 mm 42776 Ø 8 mm 42777 Ø 9 mm 42778 Ø 10 mm 42779 Ø 13 mm 42780 Operation: Made in Germany Stage 1: By pressing the push button once, the coupling is vented, whereby the plug is still secured in the sleeve. Stage 2: If the push button is pressed a second time, the plug is unlocked and can be removed safely. Order number Model Plugs with Europrofile – DN 7.4 or 7.8 > Steel coupling plugs are characterised by a longer service life compared to brass coupling plugs. Recommended for use with the above HIGH FLOW steel couplings as well as the safety venting couplings.
