The Eccentric Plug Valve body casting is BS1452nGrade 220 (ASTM A126 Class B) cast iron using high pressure moulding techniques for consistent quality and precision.Flanges are available drilled to PN16, PN10 or ANSI B16.1 Class 125. Alternative grooved or mechanical joint ends are available.
High integrity sealing is achieved by combining the advantages of a resilient, abrasion resistant u-cup seal. From vacuum to high pressure, the self-adjusting sealing system gives positive, trouble-free service and is retained independently of the plug stem or external torque device, eliminating periodic maintenance.
The round port design (up to and including DN300) with streamlined internal contours gives class leading high capacity straight through flow in the fully open position, reducing turbulence, pressure drop and the effect of erosive media. Flow of sludges and slurries is therefore also enhanced. Sizes DN350 and above have rectangular ports.
The ductile iron plug is supported on integral trunnions, and is encapsulated in an elastomeric polymer, providing leaktight shut-off in either direction, even under vacuum conditions. High integrity sealing is achieved by any of the abrasion resistant elastomers. The PTFE thrust washers prevent entry of abrasive materials into the bearings.
