Worm Gear Operated EPDM Sealing Butterfly Valve

详情

FREE-VALVEs worm gear operated EPDM sealingbutterfly valveis an economical andhigh performance valve with anEPDM lining, offering longer service life with lowermaintenance cost. Self-lubricating bearings ensures perfect guiding and turning of the shaft without seizure or premature wear. Flange gaskets are not required since the lining that extends onto the faces acts as a gasket. The bonded liner extends the lifetime of the valve ensuring there is no corrosion between the body and liner.
