Pureflex 100 Series Advanced Composite Ball Check Valves
Check Valve Body
One piece massive valve body is light weight, rugged and is corrosion resistant on the outside as it is on the inside to resist environmental attack. Available in fiberglass or carbon graphite reinforced vinyl ester or Z-CORE® epoxy materials. The valve body meets ANSI B16.10 and flange connections are compliant to ASME B16.5 Class 150. Other flange drilling options are available.
Check Valve Ball
Check valve ball is manufactured from virgin PTFE and is available in solid or hollow construction. The solid PTFE ball needs just over 1 psi to unseat when the valve is in the vertical position.
Check Valve Seat
Check Valve seat is manufactured from virgin PTFE and is designed for tight trouble free sealing in your most demanding applications. The seat is easily field repairable with only the end cap needing removal.
Flo-Check™ PFA-lined ball check valves prevent the back-flow of liquids in pipelines, prevent siphoning of pumps and eliminates pump impeller rotation in opposite direction due to back-flowing media. Flo-Check’s PFA lining provides the ultimate in chemical and permeation resistance from (-)20°F to (+)400°F and all sizes are full vacuum rated.
The FLO-VU® Sight-Float Check Valve is intended for use in vertical sampling applications and as a means of preventing vacuum scrubber contamination due to over-filling of the vertical sample leg or vessel before draining back into the sample container.
Standard construction includes type 316 stainless steel flanging, 304 hardware and PFA / glass lined wetted surfaces. Polycarbonate shield tubes are provided on all units. The hollow ball float is molded from PFA and seals into a soft seat made of a white Chemraz® fluoroelastomer.
Units have a full vacuum to 150 psi rating at temperatures from -20° up to 300°F.
Gas Purge Ring - for purging and environmental control of the annular area between the glass tube and shield.
General Purpose and Explosion Proof Light - for back-lighting through windows in difficult lighting installations.
ARV2 and ARL ball check valves are fully lined with fluoropolymer resin. No wetted metal parts are used. The valves are immune to most aggressive chemicals and are used in place of expensive exotic alloys such as titanium, Hastelloy, etc. The Flowserve Atomac ball check valve can be installed either vertically or horizontally, dependent upon application.
Full Port Design: The full port design offers excellent flow characteristics to minimize pressure loss. Low Opening Pressure: The minimum opening pressure required to unseat the ball in the vertical position is 0.07 bar (1 psi).Safety Glass: For those applications requiring a higher flow capacity, Atomac check valve type ARV/SG should be considered.
Solid PTFE Ball: The ball has the same properties asthe FEP or PFA lining material.
Borosilicate glass, in accordance with DIN 7080, is utilized to withstand temperatures, mechanical stress and corrosion.
In almost every piping system, there is a need for backflow prevention. Most piping systems utilize pumps or compressors to generate needed pressure for movement of line fluids or gases. When rotating equipment stops, flow reversal or backflow occurs. Check valves are used to stop backflow and protect rotating equipment or other mechanical devices from the sudden backflow surges that may occur. To satisfy your needs, specify Crane Check Valves — the worldwide leader of valves manufactured for the prevention of backflow.
