\nCentric “Butterfly” valves are used for ON\/OFF and flow regulation. Their principle of operation (opening and closing a quarter turn by means of a disk mounted on an axle) resembles that of ball valves, but their main advantages over them are lower cost and less weight, which eliminates the possible need for additional installation on supports.<\/p>\n

Type of body:<\/strong>
\nWafer \u2013 between flanges.<\/p>\n

Lug \u2013 between flanges with threaded LUGs. It is ALSO possible to dismantle the pipeline from one side without the need to remove the valve itself.<\/p>\n

Dimensions:<\/strong>
\nNominal diameter: from DN 32 mm up to DN 600 mm (bigger sizes on request)
\nNominal pressure: 10\/16 bar
\nWorking temperature: up to 200\u00b0C (depends on disc and sleeve material)<\/p>\n

Materials:<\/strong>
\nBody : cast iron GG25, Ductile Iron GGG50, Carbon Steel A216 WCB, Stainless Steel SS316, Polypropylene
\nDisc: Ductile Iron GGG50, Stainless Steel SS316, PTFE lined Stainless Steel SS316, Uranus B6, PVC, Polypropylene, etc.<\/p>\n

Sleeve – NBR, EPDM, FKM (Viton\u00ae), Hypalon\u00ae, Silicone, Food Grade Silicone, PTFE, etc.<\/p>\n

Operating:<\/strong>

\nManual with a gear box
\nAutomatic, with pneumatics \u2013 Doube acting or single acting with spring
\nAutomatic, with electric drive<\/p>\n

Applications:<\/strong>
