Ballcentric® Plug Valve (1/2" - 2")


The Ballcentric® Plug Valve body casting is ASTM A536 65-45-12 ductile iron using high pressure molding techniques. Threaded connection available on 1/2"-2" sizes. Flanged connection available on 2" size. Flange diameter, thickness and drilling conform to ANSI B16.1 Class 125
The valve seat shall be furnished with an overlay of corrosion and abrasion resistant epoxy
Supported on integral trunnions, the plug is totally encapsulated with an elastomer that is molded to the casting providing tight shut off even under vacuum conditions. High integrity corrosion-free sealing is achieved by a variety of abrasion resistant elastomers which protect the plug right up to the trunnions. When assembled, the light compression of the elastomers onto PTFE thrust washers prevents entry of abrasive materials into the bearings
