Swing Check ValveTSWL Swing Check ValveSWL SERIESApplications Water and Wastewater Systems Pump Discharge Valve VaultsFeatures Include Both lever-andweight and outsidelever-and-springdesigns available. OptionalAir Cushion(Commercial orBronze CylinderDesigns available). Ductile iron bodywith Ductile irondisc and 316 ssSeat standard. Valve Disc allows“full flow” throughthe valve Buna-N Rubberfaced Discs standard. Optional doubleoutside levers forweight or spring Available in sizes3” thru 36”he "SWL" series Swing CheckValve from Crispin Valve is anideal solution for most checkvalve applications. Designed completely in-house using advanced 3Dmodeling and FEA technology, theSWL offers the same Crispin quality that you’ve come to expect fromall of our products.The SWL is available in Outside Lever/Weight, Lever/Spring,Air Cushion, and Oil Control configurations. Only produced in Ductile Iron with #150 flanged ends, theSWL swing check valve is intendedfor all swing check applications upto and including a 250 psi operatingpressure.Standard with 316ss seats andavailable with a variety of industryapproved epoxy coatings, the SWLoffers flexibility in tackling hardwater and corrosive environments.OperationOnce pump pressure exceeds theback pressure on the down-streamside of the valve disc, the SWLSwing Check Valve moves the discout of the flow by displacing the seatdisc to the upper portion of the valvebody. This creates full flow throughthe unit for both water and sewage.Upon pump shut down, the discwill stroke closed when velocitybegins to slow and stop. With theincorporation of a rubberized discface, the resultant drip-tight seatingwill protect the system from costlyleakage.Design2 Body SeatThe threaded-in 316 stainlesssteel seat provides firm, water-tightretention in the body. This designcan handle repeated stroking of thetypical swing check applicationwithout vibration or loosening. Standard Rubber-Faced DiscsStandard on all sizes, the rubber-faced disc configuration provides drip-tight sealing. Adjustable PackingPerfect for standard checkvalves where expensive maintenance rebuilds are not justified, theadjustable packing allows for finetuning of sealing joints over time. Bronze and Stainless TrimStandard in all units, the SWL’sbronze and stainless steel trim provides excellent protection againstcorrosion. Limit SwitchesMountable on all valves sizes,electric limit switches are availableupon customer’s request. Full Waterway Flow AreaWith a flow area that is greaterthan or equal to the nominal valvesize, the SWL swing check valvehas a lower head loss characteristicthan a Silent Check valve, and canbe mounted in both the horizontaland vertical positions. ServiceableThe disc and clapper of theSWL can be removed from thegvalve while it is still in line.SWL Crispin Valve, 600 Fowler Ave., Berwick, PA 18603 1-800-AIR-VALV T: (570) 752-4524 F: (570) 752-4962 WWW.CRISPINVALVE.COM [email protected]
